Research interests

Research interests are primarily in the areas of heat transfer enhancement, microscale heat transfer, and biothermal applications. Heat transfer enhancement is relevant to sustainability of energy resources – a specialty that is regaining its pre-eminence. Single-phase flow and boiling heat transfer in micro- and mini-channels have applications in Energy and water conservation. While these have been under investigation over the last two decades, second generation technologies are being studied in the form of surface alterations using Carbon NanoTubes (CNTs), Nanostructured particles, and nano-fluids. The research has impact on air-cooling technologies and on two-phase bubble generation and dynamics on heat transfer and pressure drop characteristics.

Biothermal applications involve interdisciplinary research in thermodynamic and fluid-flow principles to physiological problems – specifically relating to obesity, exercise, and cardiovascular diseases in aging populations. Flow characteristics involving nano-fluids, microchannels, and wall stresses have direct applications to cardiovascular issues, cryotherapies and fluid therapies.
