My primary area of work is computational fluid dynamics (CFD). I have been working on several applications involving heat transfer, mixing and turbulence. I also investigate CFD problems involving high computational cost and try to propose high performance computing (HPC) methodologies to address them using multi-core clusters and GPGPU platforms. In last few years, I have been mostly involved in addressing flow problems with moving boundaries. My group works on developing immersed boundary method (IBM) based computationally efficient algorithms to solve moving boundary problems and we have utilized these implementations to predict flow and heat transfer in interesting engineering and biological problems including flapping wings, casting, moving fins, deformable arteries etc.
