Electrochemical Machining with Nonsymmetric Suction of Electrolyte Flow

M. Hashiguchi [1], D. Mi [1],
[1] Keisoku Engineering System Co. Ltd., Tokyo, Japan

In electrochemical machining process, it is very important to control electrolyte flow field to remove contamination such as slug, or gas to be generated by the machining process as well as heat control for electrolyte, machining tool and work piece. To reduce the overcut of workpiece, ... En savoir plus

Navier-Stokes Solutions for Flow and Transport in Realistic Porous Media

N. Abdussamie
American Bureau of Shipping, Tripoli, Libya

This paper illustrates how to set up and solve a two-dimensional flow problem having dimensions of 640 x 320 micro-meter using the Navier-Stokes equations with the help of COMSOL Multiphysics solver. The principle of our pore-scale modeling approach is composed of two steps. The first ... En savoir plus

Transient Modelling of a Fluorine Electrolysis Cell; Fully Coupled Electric Currents, Heat-Transfer, Diluted Species Transport and Laminar Bubbly Flow

R. Pretorius[1], P. L. Crouse[1], and C. J. Hattingh[2]
[1]University of Pretoria, Pretoria, Gauteng, South Africa
[2]Metallurgical Testing and Consultation (MTC) cc, Farrarmere, South Africa

A laboratory-scale fluorine reactor was simulated with COMSOL Multiphysics®. This model employs fundamental fully coupled electron-, heat-, mass- and momentum transfer (two-phase) equations to deliver a transient model of the above-mentioned reactor. Quasi-steady-state results were ... En savoir plus

A Multiphysics Approach to the Modeling of Biological Prosthetic Heart Valves

A. Avanzini[1], D. Battini[1], M. Berardi[1]
[1]Università degli Studi di Brescia, Brescia, Italy

The complex behavior of biological prosthetic heart valves was simulated. A multiphysics computational approach was adopted using different modules of COMSOL Multiphysics: the LiveLink(TM) interface was used to exchange the valve geometry with CAD, Structural Mechanics Module to set ...

Gravitational Collapse of Rectangular Granular Piles

M.H. Babaei[1], T. Dabros[2], S.B. Savage[3]
[1]Ocean, Coastal, and River Engineering, National Research Council of Canada, Ottawa, ON, Canada
[2]Natural Resources Canada, CanmetENERGY, Devon, AB, Canada
[3]Department of Civil Engineering & Applied Mechanics, McGill University, Montreal, QC, Canada

In this study, the dam-break type two-dimensional gravitational collapse of rectangular granular piles in air was numerically studied. The frictional behavior of the material was based on the von-Mises model with the Mohr-Coulomb yield surface leading to pressure and strain-rate ... En savoir plus

Simulation of Atmospheric Air Micro Plasma Jet for Biomedical Applications

J. S. Crompton [1], L. Gritter [1], K. Koppenhoefer [1],
[1] AltaSim Technologies, Columbus, OH, USA

Small-scale plasma jets in atmospheric air can produce regions of highly reactive chemistry coincident with temperatures approaching room temperature allowing his type of cold plasma jet to be used for decontamination of surfaces and sterilization of living tissue. In the device under ... En savoir plus

Evaluation of Electromagnetic Heating of a Composite Material Using COMSOL Multiphysics® Software

R. B. R. Chethan[1], A. Desale [1], V. Perumal [1], V. Dhamotharan [2],
[1] Siemens technology and services private limited, Bangalore, Karnataka, India
[2] IIT Madras, Chennai, India.

Carbon fiber as filaments or as continuously reinforced composite finds application in the electronic packages, electric vehicles, and electrical machines, owing to its excellent electromagnetic (EMI) shielding and high conductivity. Carbon fiber being good conductor of electricity (in ... En savoir plus

Computational Fluid Dynamics for Microreactors Used in Catalytic Oxidation of Propane

S. Odiba[1], M. Olea[1], S. Hodgson[1], A. Adgar[1]
[1]Teesside University, School of Science and Engineering, Middlesbrough, United Kingdom

This research deals with the design of suitable microreactors for the catalytic oxidation of volatile organic compound (VOCs), using propane as a model molecule. The microreactor considered consists of eleven parallel channels, in which an Au/Cr/γ-Al2O3-catalyzed combustion reaction ... En savoir plus

3D COMSOL Multiphysics® Model of a Plate Heat Exchanger to Support a Laboratory Teaching Environment

N. Medeiros[1], W. Clark[1]
[1]Worcester Polytechnic Institute, Worcester, MA, USA

Chemical engineering students and practitioners need an understanding of fluid flow and heat transfer inside heat exchangers. Because the flow within plate heat exchangers is difficult to visualize, we developed COMSOL Multiphysics® simulations of plate heat exchangers for students to ... En savoir plus

Dynamic Analysis of a Roller Compacted Concrete Dam
