(Water, Air, Thermal, Energy Resource, Medical and Additive Technology towards Emerging Research on Sustainability)


Dr. Bahni Ray has joined the Mechanical Engineering Department of IIT Delhi in 2017 as an Assistant Professor. She got her B. Tech & M.Tech Dual degree in 2006 from IIT, Kharagpur Mechanical Engineering Department. She received her doctorate degree in Mechanical Engineering from IIT Kanpur on 2012. After her Ph. D., she worked as a Postdoctoral researcher at Johns Hopkins University, Maryland, USA for one year and City college of New York, New York, USA for two years.


This lab works on a wide range of fundamental study and industrial applications of multiphase flow systems with main focus on drop and bubble dynamics and microchannel using numerical and theoretical tools. Research covers multiscale phenomena ranging from flow in microchannel to large drop impacts for large range of time. To study the multiphysics different in-house and open source code are used. Apart from developing numerical schemes to capture the intricate details of interfacial flow, main focus is on studying the physics explaining the different flow phenomena. The primary application of work is on ink-jet printing, emulsions, oil spill breakup in oceans, production of micro-sized drops to mention few.
