Computational Fluid Dynamics

Computational Fluid Dynamics is my main area of research. During my Ph.D., I have worked on complex fluid flow problems such as flow past a circular cylinder and its rotating counterpart. During my post-doc, I have worked on open channel flows. At IIT Mandi, my research group is working on different aspects of fluid dynamics. We have studied complex flow problem like flow past a rotationally oscillating circular cylinder using HOC scheme. We have also extended the application of HOC schemes for linear shear flow problems. We have studied shear flow past bluff body problems for single square cylinder, double and triple square cylinders arranged in parallel, series and in a triangle (for three cylinders) shape. Our computed results very efficiently depict the flow phenomena near the surface of the cylinder. We also have used the topological aspect based structural bifurcation analysis to study the vortex shedding phenomena. This structural bifurcation analysis very efficiently calculates the exact location and time of occurrence of the bifurcation points (re-circulation zones). We have observed many new flow phenomena in our studies, which have not been reported before. Also, to the best of our knowledge, this is the first time that topological aspect based structural bifurcation analysis is used to study this type of problems.

Currently, we are working on the vorticity control in flow past bluff body problems using control plates. We are also studying the fundamental aspect of heat and mass transfer in fluid flows. We have observed many interesting results which are not studied before. We are also working on different aspects of heat transfer in simple fluid and nanofluids.
