Blood Flow Patterns in a Patient Specific Right Coronary Artery with Multiple Stenoses

B. Liu[1]
[1]Department of Mathematics, Monmouth University, West Long Branch, NJ, USA

Atherosclerotic lesions preferentially develop in certain regions like bifurcations, branches, and bends [1, 2]. A possible explanation for such a preferential localization of atherosclerosis is that the geometry of the vessel influences the blood flow pattern. It suggests that the ... En savoir plus

Plasma Edge Simulations by Finite Elements using COMSOL

C. Hollenstein, and A. Howling
Ecole Polytechnique Fédérale de Lausanne, Switzerland

Finite elements using COMSOL Multiphysics have been used to simulate the edge plasma in a large area capacitively coupled RF reactor. In order to reduce numerical difficulties simplified reactor edge geometries have been used. First results show the importance of electrostatic double ... En savoir plus

Sensitivity Estimation of Permanent Magnet Flowmeter

V. Sharma[1], S. K. Dash[1], G. Vijaykumar[1], B. K. Nashine[1], B. Krishnakumar[1], P. Kalyanasundaram[1], and G. Vaidyanathan[1]
[1]Fast Reactor Technology Group, Indira Gandhi Centre for Atomic Research, Kalpakkam, Tamil Nadu, India

Permanent Magnet Flowmeter (PMFM) is a non invasive device, which is used to measure the flow of electricallyconducting sodium in Fast Breeder Reactor Circuits. PMFM works on the principle of generation of motional EMF by magnetic forces exerted on the charges in a moving conductor. In ... En savoir plus

Numerical Study of the Gas-Powder Flow from Coaxial Nozzles in Laser Metal Deposition

E. Ferreira [1], M. Dal [1], P. Peyre [1], C. Colin [2], G. Marion [3], D. Courapied [3], B. Macquaire [3],

[2] Centre des Matériaux, UMR 7633 MINES Paris Tech, Evry, France
[3] Safran, Paris, France

The Laser Metal Deposition process (LMD) is a rapid free form fabrication method which can be used to manufacture new near net shape metallic components, to repair used ones or to add functional parts on existing ones. This process is composed by multiple gas streams flowing inside a ... En savoir plus

Integrating COMSOL into a Mathematical Modeling Course for Chemical Engineers

A. Dixon, and D. DiBiasio
Department of Chemical Engineering, Worcester Polytechnic Institute, Worcester, MA, USA

The multiphysics simulation package COMSOL was incorporated into a course in mathematical modeling for chemical engineers. Our implementation for the first year of using COMSOL in the course is described, and assessment results based on examinations and student survey results are ... En savoir plus

Thermal Simulation of a Heat Pipe Tempered Injection Mould Tool

S. Kartelmeyer [1], C. Jaroschek [1], L. Fromme [1], V. Hüttemann [1], E. Moritzer [2],
[1] University of Applied Sciences Bielefeld, Department of Engineering Sciences and Mathematics, Bielefeld, Germany
[2] Paderborn University, Department of Plastics Engineering (KTP), Paderborn, Germany

An injection moulding tool developed by the FH Bielefeld is being displayed in a thermally precise way by means of COMSOL Multiphysics®. The tool is tempered through heat pipes. The performance of heat pipes is experimentally determined and depicted in a function. The function ... En savoir plus

[1] Department of Physics, Division of Materials Physics, University of Helsinki, Helsinki, Finland

High intraocular pressure (IOP) is a risk factor for glaucoma, a condition that can cause blindness. Conventional ways of measuring IOP either require contact or can be uncomfortable for the patient. We have developed a method to measure IOP from the propagation time of a wave on the ... En savoir plus

Structure of a Classical Vortex Ring

J. M. Russell [1],
[1] Florida Institute of Technology, Melbourne, FL, USA

This talk is for users of the COMSOL Multiphysics® software who, like the present author, are relative newcomers to numerical simulation but have a strong grounding in Hydrodynamics or related areas of Mathematical Physics. As part of a multi-year plan to develop proficiency in Equation ... En savoir plus
