Primary Research Theme: Aerodynamics and Fluid Mechanics
Research Group/Lab: Aerodynamic

My fundamental research lies primarily in the area of experimental fluid mechanics. I am interested, in particular, in turbulent flows and the mixing that occurs therein. In my work, scalar (e.g., temperature, moisture, chemical species/pollutant, etc.) mixing is examined with an aim to further understanding the underlying physics of many thermo-fluid processes, including combustion and pollutant dispersion into the environment. The mixing of momentum (which leads to drag) is also studied. The research is approached from a fundamental perspective in which the results are applied to engineering problems, and is performed by way of hot-wire anemometry, cold-wire (resistance) thermometry, laser-induced fluorescence and particle-tracking velocimetry.

My applied research focus on the fluid mechanical and thermal aspects of industry flows.  It is generally sponsored by industry.  Recent work has focused on the cooling of hydroelectric generators, as well as the cooling of microelectronics.
