We use computational fluid dynamics, finite element and finite volume methods, for problems with free and moving boundaries, as well as complex interfaces. Most of the problems I work on are materials processing related, usually with an industry sponsor.
I am interested in problems with compex rheology and multiple phases - e.g. liquid-liquid dispersions and particle-liquid flows. My group does both computational and experimental work in these types of systems
Our group does computer simulation and experiments in a number of important polymer processing operations, including: mixing (twin-screw extruders, static mixers, impingement mixing), die design, reactive processing, injection molding, liquid coating and rheology.
We have studied pulp processing, specifically modelling brownstock washing, the fluid mechanics of flow in pulp pads, displacement washing and the role of defoamers. A continuing interest of mine has been in the development of process models and optimization of chemical plants. I am interested in the development of problem-based learning methods in the area of process analysis.
Here is a listing of previous Master's and PhD students I have supervised and their thesis titles.
