The students at ESPNG have, since 2002, been using COMSOL Multiphysics in order to master physical phenomena and the finite element method. We developed several projects based on the modeling of physics phenomena, and, in this paper, we present projects based on Physical Vapor Transport and Magnetic Levitation. --------------------------------- Keynote speaker's biography: Jean-Marc ...

This paper presents the simulation of exhaust gas heat recovery system for an automobile using COMSOL Multiphysics®. A double pipe heat exchanger is modeled in which the tube side medium is the hot exhaust gas and the shell side medium is water. The problem is divided into three parts i.e. Laminar flow in water regime, Turbulent flow in exhaust gases and Heat Transfer in solids. They are solved ...

The main purpose of this paper is to develop a proof of concept software that can simulate the geometry of engraved surfaces and can estimate the depth and width of engraved groove and associated laser parameters. For this purpose, COMSOL has been used to simulate the moving laser beam as a source of heat over physical domain made of different materials. Through interaction modeling of ...

Matrix Assisted Pulsed Laser Evaporation (MAPLE) technique is used for the deposition of high quality biocompatible polymer thin films. During the deposition process the temperature of the laser target should be kept below 193K to assure the proper quality of both evaporation and deposition phases of the process. On a first approach COMSOL Multiphysics® was used to describe and analyze the ...

This paper presents steady and unsteady computational results obtained from numerical solutions of the full two-dimensional governing equations for annular internal condensing flows in a channel. This is achieved by tracking the “sharp” interface while solving the flow fields using COMSOL Multiphysics® and MATLAB®. The unsteady wave simulation capability is used to predict heat-transfer ...

COMSOL Multiphysics® is used to simulate a thermal transport based flow sensor, which will be embedded in a micro-channel of a Poly-methyl methacrylate (PMMA) based microfluidic device. The channel height is 100μm and for simulation purposes the lengths has been set to 1.2mm. The heater element and the two sensors are made of platinum and were modeled using Heat Transfer in Fluids, Laminar flow ...
