About me

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 sets of Onsager-consistent equations (called OBurnett and O13 equations), which are supposedly more general continuum transport equations thaen 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. We also quantified the volume of cough cloud and probability of infection from coughing, during the pandemic.
Our research work is documented in 300 journal articles and one book. The work has appeared on the cover page of prestigious journals such as the Journal of Fluid Mechanics and Physics of Fluids, and highlighted in the media on several occasions. The work has been conducted by 40+ PhD and 60+ MTech students (who are all well placed in various Industry/Academia), along with 13 Postdoctoral Fellows. Currently, I have an active research group comprising several very dedicated students and postdocs. I am serving as the Editor-in-Chief of Transactions of INAE and as Editor of ASME Journal of Heat and Mass Transfer. Our research has been recognized by the country's highest scientific honor — the Shanti Swarup Bhatnagar Prize and JC Bose National Fellowship.
