The goal of Professor Sinclair's research is to develop computational fluid dynamic (CFD) models for multiphase flow. These models employ the "two-fluid" framework and concepts from gas kinetic theory describe particle-particle interactions. Professor Sinclair's models are incorporated into the commerical CFD code Fluent, Version 4.5, which is used internationally to simulate single-phase and two-phase flows. Added understanding of the nature of the interactions between the continuous and dispersed phases, which give rise to such effects as turbulence modulation in the fluid by the presence of the particles, is gained via non-intrusive flow measurements with a three-component laser Doppler velocimeter/phase Doppler particle analyzer. A jet flow facility has been constructed and experiments are currently being conducted which focus on the effect of particle size distribution in the dispersed phase.
