My current research is on modelling fluid flows in the context of channel networks. It involves using image analysis to identify different components of a network and exploiting the properties of graph theory to solve for fluid flow. The method generally decreases the computing time by orders of magnitude, as otherwise one needs to resort to solving full fluid equations in a complicated network, which is not trivial. This work has applications in water distribution network and rivers.

My research in Phd focussed 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.

MY LATEST RESEARCH

A video showing reconstructed velocity field (right) using 50 POD modes. Left side of the video is the original velocity field. The flow is buoyancy-driven exchange flow across a horizontal vent.
