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

My 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.
