Advantages of coupling Passage®: Discrete Element Modeling (DEM) and CFD FLOW Software

By coupling PASSAGE®: DEM and FLOW software a variety of problems can be solved which can not be treated by using either one model individually. This capability allows modeling of liquids, gases, solid particles and their mixtures for many industrial problems in both micro and macro scales. It can be applied to process modeling of mixing, wetting, coating, filtration, fermentation and filling operations for applications in food, pharmaceutical, chemical, metals, plastics, glass, ceramics, powders processing and emission control.

DEM and FLOW modules can be coupled in a variety of ways depending on the application:

Many mixtures or two-phase flows require modeling of microscopic behavior of the material (e.g. air flow around solid particles. In this case DEM and FLOW modules are executed in parallel.
Industrial applications of particle flows usually involve billions of particles which cannot be efficiently modeled by DEM models. On the other hand, flow codes can not predict the material properties of mixtures or particle flows in sufficient detail due to the lack of accurate material models. In this case, DEM model is used to determine material properties for the FLOW model.

Introduction of Simulation Tools for Pharmaceutical, Food and Chemical Process Industries

Process industries generally rely on the technology of equipment manufacturers in process development. For a new material or process, equipment manufacturer proposes a solution based on experience. For example, granulation process has to be developed for a new powder. A prototype is built and tested. After some experimentation full scale equipment is built. This approach is time consuming and has certain pitfalls. If a new material or process is being developed, the manufacturer’s experience is limited. On the other hand, the process company has limited knowledge of the equipment. After a series of tests, a prototype is designed. After a prototype is built and tested, the physical properties of the material required to describe the process is measured fully for the first time. Yet, the measurements from the prototype are not always sufficient to predict the full scale process. Material and process parameters can not be scaled linearly for most material. Sometimes, major difficulties are observed only after the full scale equipment is built.

Process simulation to complement and improve process development is being introduced rather slowly. In product development, simulation tools are widely used. For designing an automobile or an airplane one cannot imagine only testing and not using simulation tools. Many times, chemical engineers or food scientists are more concerned about the properties of materials for other concerns than manufacturing. Manufacturing process is addressed after the material is developed. Thus, in pharmaceutical, food and chemical industries, optimization of manufacturing processes may hot have attracted as much attention as the product industries. On the other hand the concerns are similar: time to market, quality and efficiency in production.

In introducing simulation to process industries the following steps can be suggested:
• Early in the development of the material and the process, physical properties of the material can be measured even if a small amount of material is available in a test tube.
• This new material and process can be simulated and optimized toward the design of the prototype.
• After the prototype is built, it would be used to complement and validate the simulation model. Further optimization can be accomplished by the simulation model in shorter time than if only the prototype was used.
• Scale-up to full scale is then conducted through simulation before the full scale model is built. The critical parameters and possible difficulties can be predicted ahead of time.
• After the full scale model is built and tested, simulation models can be used for further optimization.

The above process can be conducted jointly by the material/process developer and the equipment manufacturer. It allows specific information exchange between the two parties since simulation models provide much more detailed information than what can be measured. They also provide a better understanding of critical material properties and process conditions.

During the recent years, we see more applications of simulation to process industry। Yet, the progress has been slow mainly due to the complexity of materials and processes. It is not practical to expect off the shelf software to answer all the questions for such problems. The implementation of simulation tools require software which can model the entire problem and is validated for that process. This requires close cooperation between the process and software developers. Please contact Technalysis for more details

Sand Casting Process Description, Defects, Equipment, Design
Sand casting, the most widely used casting process, utilizes expendable sand molds to form complex metal parts that can be made of nearly any alloy. Because the sand mold must be destroyed in order to remove the part, called the casting, sand casting typically has a low production rate. The sand casting process involves the use of a furnace, metal, pattern, and sand mold. The metal is melted in the furnace and then ladled and poured into the cavity of the sand mold, which is formed by the pattern. The sand mold separates along a parting line and the solidified casting can be removed. The steps in this process are described in greater detail in the next section...more at http://www.custompartnet.com/wu/SandCasting

Understanding the Relationship Between Filling Pattern
and Part Quality in Die Casting

1.0 Introduction
The overall objective of this research project was to investigate phenomena involved in the
filling of die cavities with molten alloy in the cold chamber die-casting process. It has long been
recognized that the filling pattern of molten metal entering a die cavity influences the quality of
die-cast parts. Filling pattern may be described as the progression of molten metal filling the die
cavity geometry as a function of time. The location, size and geometric configuration of points
of metal entry (gates), as well as the geometry of the casting cavity itself, have great influence on
filling patterns. Knowledge of the anticipated filling patterns in die-castings is important for
designers. Locating gates to avoid undesirable flow patterns that may entrap air in the casting is
critical to casting quality – as is locating vents to allow air to escape from the cavity (last places
to fill). Casting quality attributes that are commonly flow related are non-fills, poor surface
finish, internal porosity due to trapped air, cold shuts, cold laps, flow lines, casting skin de-
lamination (flaking), and blistering during thermal treatment more...

TU Delft - CFD in drinking water treatment

CFD in drinking water treatment
According to the new Water Supply Act, the removal of micro-organisms in the purification of water must meet very stringent requirements. This means that the hydraulic flow of the water in purification systems such as ozonisation and UV-desinfection must also comply with very stringent requirements, since short-circuit flows must in no way occur as they strongly reduce the efficiency. The efficiency of peripheral facilities of sewer systems, at overflow locations, also strongly depend on the flow through the peripheral facility. The efficiency of peripheral facilities of sewer systems, at overflow locations, also strongly depend on the flow through the peripheral facility.In view of the large variation in hydraulic design of peripheral facilities, rationalisation seems to be called for. Finally, the number of breakdowns of sewage pumping-stations, an important cause of overflow, can be reduced by improving the hydraulic design of the pump pit, such that sediment can no longer accumulate at the inlet. So, these research projects focus on describing the flow in treatment plants, pump pits and peripheral facilities by means of CFD modelling.
Amsterdam Water Supply AWS of the Netherlands produces some of the cleanest drinking water in the world, almost 100 million cubic meters per year in fact. They take the water from the Rhine River and purify it in a 14-step process. During the ozone treatment, ozone gas reacts with particular micropollutants in a turbulent tank and inactivates pathogenic micro-organisms. In the perfect world, the water and the ozone gas mix and stay in the reactor just long enough to knock out the targeted pollutants.

AbstractDetailed level Computational Fluid Dynamics (CFD) models for fans and radial blowers involve information about blade geometry, flow angles, blade rotational speed, and flow approach velocities. Accurate simulations of such models require large numbers of mesh points which is beyond the allocated time and available resources for engineering design cycles. When dealing with system or board level thermal analysis, where a fan or a blower is among many components to be modeled, a "macro" representation of a fan or a blower is preferred. A "macro" model for a fan is a plane surface that induces pressure across as the flow passes through it. The pressure-airflow relationship is taken from the fan curve provided by the fan manufacturer. A "macro" model for a radial blower is more involved because of the 90/spl deg/ flow turn inside the blowers housing and induced flow swirl caused by impeller blades. The need to capture the flow turn and induced swirl becomes more pronounced when simulating multiple interacting blowers inside a blower tray. In this paper, a systematic approach is presented to design the blower macro from the existing fan model. Icepak CFD results for the blower tray have been analyzed and compared with the experiments conducted at Applied Thermal Technologies Laboratory. Typical use of a three-fan blower tray in a system representing telecommunication applications is also presented.

"A discrete element algorithm is a numerical technique which solves engineering problems that are modeled as a large system of distinct interacting general shaped (deformable or rigid) bodies or particles that are subject to gross motion. Engineering problems that exhibit such large scale discontinuous behavior cannot be solved with a conventional continuum based procedure such as the Finite Element Method. The discrete element procedure is used to determine the dynamic contact topology of the bodies. It accounts for complex non-linear interaction phenomena between bodies and numerically solves the equations of motion. Since the DEM is a very computationally intensive procedure, many existing computer codes are limited to modeling either two-dimensional or small three-dimensional problems that employ simple body geometries.

Abstract: This paper details a study of the effects of multiple torque converter design and operating point parameters on the resistance of the converter to cavitation during vehicle launch. The onset of cavitation is determined by an identifiable change in the noise radiating from the converter during operation, when the collapse of cavitation bubbles becomes detectable by nearfield acoustical measurement instrumentation. An automated torque converter dynamometer test cell was developed to perform these studies, and special converter test fixturing is utilized to isolate the test unit from outside disturbances. A standard speed sweep test schedule is utilized, and an analytical technique for identifying the onset of cavitation from acoustical measurement is derived. Effects of torque converter diameter, torus dimensions, and pump and stator blade designs are determined.

Chromatography
This page covers topics common to the different types of chromatography. Links to the separate pages for the sub-categories of chromatography are below:
TLC
Column Chromatography
GC
Overview of common undergraduate chromatography techniques.
Three types of chromatography are routinely used in the organic chemistry teaching labs:
Column Chromatography
Thin Layer Chromatography (TLC)
Gas Chromatography (GC)
In these (and all types of) chromatographies, a mixture is separated by distributing the components between a stationary phase and a mobile phase. The mixture is first placed on the stationary phase (a solid or a liquid) and then the mobile phase (a gas or a liquid) is allowed to pass through the system.
Column chromatography: The stationary phase is a powdered adsorbent which is placed in a vertical glass column. The mixture to be analysed is loaded on top of this column. The mobile phase is a solvent poured on top of the loaded column. The solvent flows down the column, causing the components of the mixture to distribute between the powdered adsorbent and the solvent, thus (hopefully) separating the components of the mixture so that as the solvent flows out of the bottom of the column, some components elute with early collections and other components elute with late fractions.
Thin Layer Chromatorgraphy: The stationary phase is a powdered adorbent which is fixed to a aluminum, glass, or plastic plate. The mixture to be analyzed is loaded near the bottom of the plate. The plate is placed in a reservoir of solvent so that only the bottom of the plate is submerged. This solvent is the mobile phase; it moves up the plate causing the components of the mixture to distribute between the adsorbent on the plate and the moving solvent, thus separating the components of the mixture so that the components are separated into separate "spots" appearing from the bottom to the top of the plate.
Gas Chromatography: The stationary phase is a high-boiling liquid. (Think of it as a viscous oil, or waxy substance.) This high-boiliing liquid is packed into a long, narrow glass or metal column. The mixture to be analyzed is loaded by syringe into the beginning of this column. The mobile phase is an inert gas which continuously flows through the column. The components of the mixture distribute between the stationary high-boiling liquid (these components are either condensed or absorbed on the high-boiling liquid) and mobile gas (vapor) phase moving through the column. The gaseous mixture flows through a detector at the end of the column and if it has been successfully separated, the components show as different 'blips' or peaks on a recorder... http://orgchem.colorado.edu/hndbksupport/chrom.html

Numerical Simulations and Experimental Study of Liquid Metal Flow Around Sand Core

This paper presents the results of experimental and numerical studies of the hot distortion phenomenon in the phenolic urethane cold box systems used in metal casting. Dual Pushrod Dilatometry has been used to measure a thermal expansion/contraction of phenolic urethane cold box sand core specimens at temperatures ranging from 20°C to 600°C. High temperature tensile tests showed that the tensile strength of the phenolic urethane cold box sand cores is significantly affected by the bench life, temperature and binders level. High temperature hot distortion furnace tests on cylindrical cores showed that some coatings increase the temperature limit when distortion starts, but application of coating cannot prevent distortion. The hot distortion test during metal casting showed that regardless of the application of coating, the type of coating, and anti-veining additives, all cores with density greater than the density of the molten metal (magnesium alloy) were significantly distorted. Numerical simulations of the liquid metal flow around the cylindrical sand core and analysis of dynamic forces acting on the core during the fill process showed that a buoyancy force is the major contributor to the hot distortion. It is concluded that the one of the solutions in preventing the hot distortion of sand cores is optimizing their weight, which will balance the buoyancy force and will bring the resultant force to the minimum. The hot distortion test castings using optimized sand cores with density almost equal to the density of the molten magnesium proved our predictions, and hot distortion has been prevented... http://scitation.aip.org/getabs/servlet/GetabsServlet?prog=normal&id=JFEGA4000128000003000541000001&idtype=cvips&gifs=yes

Capping Mechanisms during Pharmaceutical Powder Compaction

Capping Mechanisms during Pharmaceutical Powder Compaction

Wednesday, 26 April 2006 - 2:40 PM197f
Capping Mechanisms during Pharmaceutical Powder Compaction
Chuan-Yu Wu, Department of Chemical Engineering, Formulation Engineering Research Centre, University of Birmingham, Edgbaston, Birmingham, B15 2TT, United Kingdom
Pharmaceutical tablets are the most popular dosage form for drug delivery. The tablets are generally produced by compacting dry powders. During pharmaceutical powder compaction, the tablets produced need to sustain their integrity during the process and have to be strong enough to sustain any possible load experienced during the post-compaction processes, such as coating, packing and handling. Hence, any defects, such as chipping, capping and laminating, are not tolerable during pharmaceutical powder compaction. However, such defects are common problems during the tabletting process. Therefore, understanding the failure mechanisms of these defects has attracted considerable attention.
In this paper, only the mechanisms of capping were considered. Previous studies on capping during pharmaceutical powder compaction have been reviewed. capping mechanisms have been further explored by conducting a combined experimental and computational study on pharmaceutical powder compaction. An instrumented hydraulic press (also known as compaction simulator) has been used to investigate the powder behaviour during the compaction. In addition, an instrumented die has also been used, which enable the material properties to be extracted for some real pharmaceutical powders. Close attentions have been paid to the occurrence of capping during tabletting. An X-ray Computed Microtomography system has also used to examine the internal failure patterns of the tablets produced using the compactions simulator. Furthermore, pharmaceutical powder compaction has also been analysed using finite element (FE) methods, in which the powder was modelled as an elastic-plastic continuum medium following Drucker-Prager-Cap yield criteria and the material properties were determined from the uniaxial compaction with an instrumented die. In both experimental and numerical studies, cylindrical tablets with different surface curvatures, including Flat-face round tablets and convex tablets, were considered.
From the experimental observation, it is clear that different capping patterns were obtained for different shaped tablets: cone-shaped capping for flat-faced tablets and normal capping with essentially horizontal failure surface for convex tablets. It was also observed in the experiments that capping takes place at the early stage of decompression (unloading), i.e., the top punch begins to withdraw. Close examination of FEA results reveals that the capping is associated with an intensive shear band developed at the early stage of unloading for all cases considered. Therefore, the combined experimental and numerical studies demonstrated that the intensive shear bands developed at the early stage of unloading are responsible for the occurrence of capping.

Freeze Dryer Characterization using Water Sublimation Tests and Applications for Lyocycle Scale-Up

2007-08-29T07:01:00.000-07:00

Conference Module

Description:
Purpose: To compare lab, pilot, and production-scale freeze dryers using water sublimation tests. Sublimation tests will be used to (i) identify shelf to shelf variation and map the lyophilizer with respect to sublimation rate (ii) evaluate the maximum sublimation rate attainable without overloading the freeze dryer (iii) calculate the vial heat transfer coefficient for various locations in the freeze dryer.
Methods: Using Water for Injection (WFI), the sublimation rate, determined gravimetrically, was evaluated for lab, pilot, and production-scale freeze dryers. Steady-state heat and mass transfer relationships relevant to freeze drying were used to calculate the heat transfer coefficients and overloading conditions for each freeze dryer evaluated. The heat transfer coefficient was used to model primary drying using PassageÒ Freeze Drying software.
Results: The sublimation tests in trays demonstrated that failure of the freeze dryer (e.g. loss of pressure control) might occur if the sublimation rate exceeds the thermal load capacity. The sublimation tests also demonstrated that the sublimation rate in vials increased towards the rear of the freeze drying chamber (closest to the pipe separating chamber and condenser) and typically the lowest sublimation rates were observed on the middle shelf, indication of the “coldest zone” of the lyophilizer. The heat transfer coefficient for various locations on a shelf is also dependent on the scale of the freeze dryer. For example the heat transfer coefficient for center vials in a pilot-scale freeze dryer was approximately half of the heat transfer coefficient calculated for center vials in a lab-scale freeze dryer. The PassageÒ Freeze Drying software predicted relative drying times that were consistent with experimental data for sublimation endpoint for various size lyophilizers.
Conclusion: Data acquired from water sublimation tests can be used to ensure the freeze dryer can sustain a thermal load for specified lyocycle conditions. Sublimation test data is also used to determine hot/cold zones in the lyophilizer that should be identified as areas interest for post-lyophilization testing such as water content and reconstitution time. Sublimation test data can be also be used to compare equivalence of various capacity dryers and the PassageÒ Freeze Drying software can be used to predict the endpoint of ice sublimation which is extremely valuable for lyocycle scale-up.

Die casting software

Advantages of dieCAS® Software
Unlike other general purpose casting analysis products, dieCAS® software is specialized to die casting. As a result, it can take advantage of die casting’s characteristics and achieve enormous savings in analysis time, without sacrificing solution accuracy.

The analysis is based on a shell-like finite element model of the casting together with a three-dimensional finite element model of the die. This combination creates the following unique advantages:

Direct Calculation of the Steady Periodic Die Temperatures. Unlike all other commercial systems, dieCAS® software does not have to analyze the leading process transient to calculate die temperatures at steady state. This reduces computer time from several days (and even weeks for a large die) to a few hours.

Simplified Model Creation & Editing. Because dieCAS® uses three-dimensional unstructured finite element meshes automatically, the user has to generate only the surface mesh to create the volume mesh automatically. This simplifies the process of both creating and editing the die model. Since cooling lines are represented by one-dimensional elements in the die interior, they can be altered independently of the die model.

Rapid Analysis of Cavity Fill. The unique two-dimensional representation of the die cavity enables an extremely fast analysis of liquid metal flow during cavity fill. Cavity fill run times for even large castings are just a few hours, compared with several days for conventional methods.

Complete Thermo-Mechanical Model of Casting and Die Distortion. Thermal distortions and residual stresses are calculated with minimal user input after the completion of filling and thermal analyses. All Results are available in about an hour, even on very large dies

The nonsteady state modeling of freeze drying: in-process product temperature and moisture content mapping and pharmaceutical product quality applications.
M J Pikal, S Cardon, Chandan Bhugra, F Jameel, S Rambhatla, W J Mascarenhas, H U Akay
INTRODUCTION: Theoretical models of the freeze-drying process are potentially useful to guide the design of a freeze-drying process as well as to obtain information not readily accessible by direct experimentation, such as moisture distribution and glass transition temperature, Tg, within a vial during processing. Previous models were either restricted to the steady state and/or to one-dimensional problems. While such models are useful, the restrictions seriously limit applications of the theory. An earlier work from these laboratories presented a nonsteady state, two-dimensional model (which becomes a three-dimensional model with an axis of symmetry) of sublimation and desorption that is quite versatile and allows the user to investigate a wide variety of heat and mass transfer problems in both primary and secondary drying. The earlier treatment focused on the mathematical details of the finite element formulation of the problem and on validation of the calculations. The objective of the current study is to provide the physical rational for the choice of boundary conditions, to validate the model by comparison of calculated results with experimental data, and to discuss several representative pharmaceutical applications. To validate the model and evaluate its utility in studying distribution of moisture and glass transition temperature in a representative product, calculations for a sucrose-based formulation were performed, and selected results were compared with experimental data.

Castro MA, Putman CM, Cebral JR.
School of Computational Sciences, George Mason University, Fairfax, Va.
PURPOSE: The purpose of this study is to show the influence of the upstream parent artery geometry on intraaneurysmal hemodynamics of cerebral aneurysms. METHODS: Patient-specific models of 4 cerebral aneurysms (1 posterior communicating artery [PcomA], 2 middle cerebral artery [MCA], and 1 anterior communicating artery [AcomA]) were constructed from 3D rotational angiography images. Two geometric models were constructed for each aneurysm. One model had the native parent vessel geometry; the second model was truncated approximately 1 cm upstream from the aneurysm, and the parent artery replaced with a straight cylinder. Corresponding finite element grids were generated and computational fluid dynamics simulations were carried out under pulsatile flow conditions. The intra-aneurysmal flow patterns and wall shear stress (WSS) distributions were visualized and compared. RESULTS: Models using the truncated parent vessel underestimated the WSS in the aneurysms in all cases and shifted the impaction zone to the neck compared with the native geometry. These effects were more pronounced in the PcomA and AcomA aneurysms where upstream curvature was substantial. The MCA aneurysm with a long M1 segment was the least effected. The more laminar flow pattern within the parent vessel in truncated models resulted in a less complex intra-aneurysmal flow patterns with fewer vortices and less velocity at the dome. CONCLUSIONS: Failure to properly model the inflow stream contributed by the upstream parent "

Discrete element method - Wikipedia, the free encyclopedia

Discrete element method
From Wikipedia, the free encyclopedia
Jump to: navigation, search
The term discrete element method (DEM) is a family of numerical methods for computing the motion of a large number of particles like molecules or grains of sand. The method was originally applied by Cundall in 1971 to problems in rock mechanics. The theoretical basis of the method was detailed by Williams, Hocking, and Mustoe in 1985 who showed that DEM could be viewed as a generalized finite element method. Its applications to geomechanics problems is described in the book Numerical Modeling in Rock Mechanics, by Pande, G., Beer, G. and Williams, J.R.. Good sources detailing research in the area are to be found in the 1st, 2nd and 3rd International Conferences on Discrete Element Methods. Journal articles reviewing the state of the art have been published by Williams, and Bicanic (see below). A comprehensive treatment of the combined Finite Element-Discrete Element Method is contained in the book The Combined Finite-Discrete Element Method by Munjiza. The method is sometimes called molecular dynamics (MD), even when the particles are not molecules. However, in contrast to molecular dynamics the method can be used to model particles with non-spherical shape. The various branches of the DEM family are the distinct element method proposed by Cundall in 1971, the generalized discrete element method proposed by Hocking, Williams and Mustoe in 1985, the discontinuous deformation analysis (DDA) proposed by Shi in 1988 and the finite-discrete element method proposed by Munjiza and Owen in 2004.
Discrete element methods are processor intensive and this limits either the length of a simulation or the number of particles. Advances in the software are beginning to take advantage of parallel processing capabilities (shared or distributed systems) to scale up the number of particles or length of the simulation. An alternative to treating all particles separately is to average the physics across many particles and thereby treat the material as a continuum. In the case of solid-like granular behavior as in soil mechanics, the continuum approach usually treats the material as elastic or elasto-plastic and models it with the finite element method or a mesh free method. In the case of liquid-like or gas-like granular flow, the continuum approach may treat the material as a fluid and use computational fluid dynamics.

WBM: "Discrete Element Modelling
There are numerous engineering processes in the mining and minerals processing industries, such as the flow of coal through a chute or the comminution of material in a ball mill, that can not be solved using continuum based methods (i.e. the methods used in finite element modelling or computational fluid dynamics packages).
In contrast to continuum methods, the discrete element method (DEM) is a technique where the mechanics of thousands of interacting, individual elements are computed. Any geometry can be configured and the properties of the Particle-Particle and Particle-Boundary collisions can be adjusted to suit the materials. In a basic analysis, each particle or element would represented as a simple sphere, however these may be combined together to generate complex shapes observed in real world problems. Real world physics, such as friction, fracture, adhesion and cohesion, also can be incorporated into the simulation.
By explicitly modelling the dynamic motion and mechanical interactions of each body or particle in the physical problem, the simulation provides a detailed description of the velocities, positions, forces and collision events acting on each body or particle, at any given time during the simulation.
The information provided through DEM analysis can be used to investigate issues such as power requirements and wear rates for mechanical components, as well as material specific issues such as comminution rate, chute and hopper blockage and dust formation."

Navier-Stokes equations

2006-04-27T06:02:00.000-07:00

Navier-Stokes equations : "Navier-Stokes equations
The Navier-Stokes equations, named after Claude-Louis Navier and George Gabriel Stokes, are a set of equations that describe the motion of fluid substances like liquids and gases. These equations establish that changes in momentum (acceleration) of the particles of a fluid are simply the product of changes in pressure and dissipative viscous forces (similar to friction) acting inside the fluid. These viscous forces originate in molecular interactions and dictate how sticky (viscous) a fluid is. Thus, the Navier-Stokes equations are a dynamical statement of the balance of forces acting at any given region of the fluid.
They are one of the most useful sets of equations because they describe the physics of a large number of phenomena of academic and economic interest. They are useful to model weather, ocean currents, water flow in a pipe, motion of stars inside a galaxy, flow around an airfoil (wing). They are also used in the design of aircraft and cars, the study of blood flow, the design of power stations, the analysis of the effects of pollution, etc.
The Navier-Stokes equations are differential equations which describe the motion of a fluid. These equations, unlike algebraic equations, do not seek to establish a relation among the variables of interest (e.g. velocity and pressure), rather they establish relations among the rates of change or fluxes of these quantities.

Fluid dynamics is the subdiscipline of fluid mechanics that studies fluids (liquids and gases) in motion. The discipline has a number of subdisciplines, including aerodynamics (the study of gases) and hydrodynamics (the study of liquids). Fluid dynamics has a wide range of applications, including calculating forces and moments on aircraft, determining the mass flow rate of petroleum through pipelines, predicting weather patterns. Some of its principles are even used in traffic engineering, where traffic is treated as a continuous fluid.
Fluid dynamics offers a mathematical structure, which underlies these practical disciplines, that embraces empirical and semi-empirical laws, derived from flow measurement, used to solve practical problems. The solution of a fluid dynamics problem typically involves calculating for various properties of the fluid, such as velocity, pressure, density, and temperature, as functions of space and time." more... http://en.wikipedia.org/wiki/Fluid_dynamics

From Wikipedia, the free encyclopedia
(Redirected from Computational Fluid Dynamics)
Jump to: navigation, search
Computational fluid dynamics (CFD) is the use of computers to analyze problems in fluid dynamics.
The most fundamental consideration in CFD is how one treats a continuous fluid in a discretized fashion on a computer. One method is to discretize the spatial domain into small cells to form a volume mesh or grid, and then apply a suitable algorithm to solve the equations of motion (Euler equations for inviscid, and Navier-Stokes equations for viscid flow). In addition, such a mesh can be either irregular (for instance consisting of triangles in 2D, or pyramidal solids in 3D) or regular; the distinguishing characteristic of the former is that each cell must be stored separately in memory. Lastly, if the problem is highly dynamic and occupies a wide range of scales, the grid itself can be dynamically modified in time, as in adaptive mesh refinement methods more... http://en.wikipedia.org/wiki/Computational_Fluid_Dynamics
If one chooses not to proceed with a mesh-based method, a number of alternatives exist, notably :
smoothed particle hydrodynamics, a Lagrangian method of solving fluid problems,
Spectral methods, a technique where the equations are projected onto basis functions like the spherical harmonics and Chebyshev polynomials
Lattice Boltzmann methods, which simulate an equivalent mesoscopic system on a Cartesian grid, instead of solving the macroscopic system (or the real microscopic physics).
It is possible to directly solve the Navier-Stokes equations for laminar flow cases and for turbulent flows when all of the relevant length scales can be contained on the grid (a Direct numerical simulation). In general however, the range of length scale"

Compression molding -

2006-04-21T06:39:00.000-07:00

Compression molding : "Compression molding is a method of molding in which the molding material, generally preheated, is first placed in an open, heated mold cavity. The mold is closed with a top force or plug member, pressure is applied to force the material into contact with all mold areas, and heat and pressure are maintained until the molding material has cured. The process employs thermosetting resins in a partially cured stage, either in the form of granules, putty-like masses, or preforms. Compression molding is a high-volume, high-pressure method suitable for molding complex, high-strength fiberglass reinforcements. Advanced composite thermoplastics can also be compression molded with unidirectional tapes, woven fabrics, randomly orientated fiber mat or chopped strand. The advantage of compression molding is its ability to mold large, fairly intricate parts. Compression molding produces fewer knit lines and less fiber-length degradation than injection molding.
