Research interests
Mathematical modeling
Computational modeling of physical phenomena (heat transfer, fluid flow, viscoelastic materials)
Computational Tribology
Developing accurate, and computationally efficient reduced-order models, i.e., simpler alternatives to the direct numerical simulation of the fundamental conservation laws and constitutive relations.
Analyzing Tribological systems; two (and three) dimensional lubricated contacts undergoing relative motion, exhibiting complex physics for example, lubricant cavitation, liquid and/or gas compressibility, thermophysical variation in lubricant properties etc.
Biotribology; modeling systems in the human body conforming to lubrication theory and exhibiting strong viscoelastic effects for example, human joint lubrication, eye lid movement forming tear films, blood flow etc.
Efficient numerical approaches
Fully-(semi) Implicit numerical approaches for coupled system of highly non-linear equations using the Finite Difference, and Finite Volume Methods.
Grid transformation techniques for treating complex, and curved domains, in particular lubricated channels of arbitrary shape.
Sustainable Energy Systems
Design and analysis of renewable energy systems such as, concentrating solar thermal (CSP), molten salt receivers, solar photovoltaic systems etc.
