My research focuses on buoyancy-driven turbulent flows. I have performed experiments on exchange flows across horizontal vent and vertical vent (think lock-exchange, only a smaller tank). These flows have implications in natural ventilation and fire-fighting as well as other industries. I use standard experimental techniques like particle image velocimetry (PIV) and planar laser induced fluorescence PLIF.
