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 ...

3D Modeling and Simulation of the Electromagnetic and Thermal Properties of Microwave and Millimeter Wave Electronics Packages

J. Ding, and D. Linton
Queen’s University, Belfast

The COMSOL Multiphysics package has been used in this work to model and simulate the electromagnetic and thermal properties of GaAs pHEMT based Monolithic Microwave Integrated Circuits (MMIC), and a multi-chip millimeter wave package including a Low Temperature Co-fired Ceramic (LTCC) antenna array. Embedded shielding ground planes inside the ceramic and silicon carriers have been studied. The ...

Microstructural Modelling using COMSOL Multiphysics

Z. Huang, and P. Conway
Wolfson School of Mechanical and Manufacturing Engineering
Loughborough University

This paper presents models of microstructures using COMSOL Multiphysics. In particular, solder joints and bumps are investigated and diffusion of species from the substrate to the interface.

The Significance of Coupling in 3D Modelling of Acoustic Wave Propagation in a Cavity Containing Air and Porous Absorbent

L. Kelly, Y.W. Lam, and M. Avis
Research Institute for the Built and Human Environment, University of Salford

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 ...
