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 ...

The Oldroyd-B family of viscoelastic fluids are notoriously difficult to model numerically. Standard Galerkin finite element methods are prone to numerical oscillations, and solutions break down as fluid elasticity increases. The situation can be remedied to a certain degree however through the addition of weak stabilisation terms to the Galerkin formulation. We present a stabilised ...

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.
