Fluid Mechanics; Heat Transfer

Major Professional Contributions:

I work in the fields of Fluid Mechanics and Heat Transfer using experimental, theoretical and simulations tools. My research group's problems are mainly drawn from the areas of Microfluidics and Turbulent flows. Among our research interests are: development of innovative microdevices for various applications; theoretical development of higher-order continuum transport equations and related experiments; synthetic jet and microchannel based cooling of electronic devices; wake interaction from multiple bodies; etc. We have developed a microdevice for blood-plasma separation; also microdevices for three-dimensional hydrodynamic focusing, and for maintaining constant wall temperature. We have provided the first analytical solution of the Burnett equation (a higher-order continuum transport equation), for any configuration. Further, keeping the limitations of Burnett and Grad equations in mind, we derived a new set of Onsager-consistent equations, which are supposedly more general continuum transport equations then the Navier-Stokes equations. We have demonstrated synthetic jet and microchannel based device for cooling of electronic devices requiring small working distance and input power. Our research work is documented in over 180 journal articles. The work has appeared on the cover page of prestigious journals such as the Journal of Fluid Mechanics and highlighted in the media. The work has been conducted by 23 PhD and 50 MTech students (who are all well placed in various Industry/Academia), along with 6 Postdoctoral Fellows. Currently, I have an active research group comprising several very dedicated students, postdocs and project staff. I am serving as the Editor of Experimental Thermal and Fluid Science and Sadhana; also as Editorial Board Member of Nature Scientific Reports along with two other journals.
