COMSOL Multiphysics was used to simulate the heat flux from battery cells via conjugate heat transfer physics which consist of laminar flow and heat transfer in solids and fluids. Laminar flow function was used to simulate natural convection of air within the sealed enclosure. Heat ... Mehr lesen
Three efficient alternatives to the model in COMSOL’s thermoacoustics interface are presented. The higher efficiency of these models are explained from theory and are demonstrated by means of two examples. Mehr lesen
Although we know the physics inside a media where the sound waves propagate, determination of material\'s or structure\'s sound reduction index is not an easy task. The lack of good engineering solutions proves the point. The only reliable way to calculate the sound reduction index is ... Mehr lesen
Thomas Herrmannsdörfer got his PhD in experimental physics from the University of Bayreuth in 1994. In 1995, he received the Research Award of the Emil-Warburg-Foundation while he worked at the DFG-Graduiertenkolleg Bayreuth. From 1995 – 1998 he worked as a scientist at Hahn-Meitner ... Mehr lesen
Eddy current testing (ECT) is widely used to check the integrity of electrically conducting parts and notably to detect flaws. It is based on the interaction between a probe and the part under testing. The finite element method (FEM) is well fitted to the modelling of these kinds of ... Mehr lesen
This paper describes the Virtual Prototype of a Dielectric Window or High Power Microwave Vacuum Tubes and Linear Accelerators. Design formulas are provided and Computer Aided Design techniques based on COMSOL Multiphysics® software are proposed. The virtual prototype considers the ... Mehr lesen
The Thomson coil’s (TC) inherent characteristics are appropriate to meet the needs of high speed actuators for mechanical switching devices in so-called smart grids. This is due to the massive forces that it can exert in the time scale of milliseconds. A coupled COMSOL Multiphysics model ... Mehr lesen
The purpose of this study is to predict, with a multiphysics model, the degradation area of a composite material when a current is injected into the material. The main physical phenomenon is an exothermic reaction, with an irreversible nonlinear variation of the electrical conductivity. ... Mehr lesen
This work presents the application of mathematical methods of model order reduction (MOR) for automatic generation of highly accurate, compact models for wireless power transfer systems. We apply a block two-sided second order Arnoldi algorithm to automatically compute a compact model, ... Mehr lesen
A Helmholtz resonator type acoustic sensor has been designed using analytical method and finite element modeling software, COMSOL Multiphysics®. The acoustic sensor is an aluminium double frustum, hour glass, shaped with the resonator at the bottom and an acoustic horn above to amplify ... Mehr lesen
