Research Area


Major Field of Interest: Computational Fluid Dynamics; Micro- and Nanofluidics Modelling, Numerical Analysis



My research centers on Computational Fluid Dynamics, which involves theoretical/ analytical analysis and numerical mathematical modelling incorporating inherently non-linear effects. We have made important contribution in understanding several complicated fluid flow phenomena such as, steady/ unsteady flow separation, vortex breakdown, fluid-body interactions, heat transfer, electro-hydrodynamics of rigid and soft colloids and transport phenomena in microfluidics. A significant part of my work focuses on the development of advanced numerical algorithms to compute nonlinear partial differential equations.

We have done several important studies on fluid-body interactions and its influence on heat transfer and vortex shedding behind bluff body. Our works on suppression of vortex shedding and augmentation of heat transfer through inclusion of porous sheath is noteworthy.

We have demonstrated unique mathematical and numerical models to study ionic and bio-molecular transport as well as ion separation and enhancement of electro-osmotic flows through micro- and nanochannels applicable to microfluidic devices. These models were supplemented by asymptotic analysis and experimental results. We have made significant contribution to analyze the non-linear effects on electrokinetic transport of charged rigid colloids, soft particles and polyelectrolytes in electrolyte or hydrogel medium.
