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 ...

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 ...
Self Heating Effects and Equilibrium Rise Times within Micro Silicon Thermistors Operating Within a Gas Liquid Interface
R.Osborne, and K. Dawkins
University of Birmingham
This paper considers the thermal behaviour of an array of micro-silicon thermistors operating within a liquid/gas interface for fluid level sensing applications. COMSOL Multiphysics has been used to model and simulate the transient multiphysics model and calculate the overall thermal flux, the steady-state condition and time taken to obtain steady thermal balance.
The Significance of Coupling in 3D Modelling of Acoustic Wave Propagation in a Cavity Containing Air and Porous Absorbent

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 ...
