This document presents a way to model the resonances for magnetostrictive Surface Acoustic Wave (SAW) devices with the structural mechanics module of COMSOL Multiphysics. Lamb and surface modes were identified by simulation of the frequency response. A first approach was also taken to introduce damping to the model. The results from the model were compared to the data from a real device ...

A multidimensional, multicomponent, isothermal and dynamic model has been developed. It simulates the mass transport phenomena taking place in the fuel/air channel, the porous electrodes and the electrolyte of a planar SOFC. It allows prediction of the species composition profiles throughout the SOFC. For the numerical solution of the model equations, the finite element based software ...

Droplets spray deposition is an important materials process in which materials in the form of particulates or droplets (a mixture of liquid, semisolid and solid) are projected onto an arbitrary collecting surface and consolidate to build up a thin-layer coating or a bulk preform. Droplets depositing at the collecting surface adds new materials and inputs new thermal energy continuously onto the ...

This study examines acoustic wave propagation in air and porous media in three dimensions using numerical models; in particular it looks at the significance of the coupling effect between the air and porous layer. The numerical model consist of a layer of air and a layer of porous absorbent which are modelled as equivalent fluid and are characterised by complex characteristic impedance based ...
