Improved Temperature Standards Using COMSOL Multiphysics

J.V. Pearce
National Physical Laboratory, Teddington, Middlesex

This paper describes the use of COMSOL Multiphysics to evaluate the propagation of the liquid-solid interface in fixed point crucibles, and the resulting temperature distribution throughout the system as the phase transition progresses. This enables a robust identification of the features of the melting curve corresponding to physical phenomena such as the liquidus point, and also enhances the ...

Finite Element Analysis of Resonant Frequencies in Surface Acoustic Wave (SAW) Devices

G. Scheerschmidt, K.J. Kirk, and G. McRobbie
University of Paisley

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 ...

A Generic Algorithm for Modelling Thermal Dynamics with a Moving Boundary Using COMSOL Multiphysics

J. Mi, and P. Grant
University of Oxford

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 ...
