Biography

My research interests lie in the area of computational methods for fluid flow and heat transfer problems. Currently I am working on the application of AI libraries for very large scale flow simulation of urban flows and pollution modelling in collaboration with Imperial College London. I am also working on coarse mesh numerical methodology incorporating Immersed Boundary Method (IBM) for fluid flow and heat transfer physics. My research area also include computational investigation of the bio-heat transfer and arterial flows. Our group at TIET Patiala have developed in-house code for multi-dimensional tumor model simulating magnetic nanoparticle hyperthermia for tumor treatment using finite volume method (FVM). The numerical investigations of hemodynamic environment in vascular geometries reconstructed from patient specific vascular morphologies plays a role in the detection, and treatment of arterial disease. My other areas of research also include analysis and developments of composite Type IV hydrogen storage systems.
