  Research Highlights:

Liquid atomization is a critical pre-combustion process for efficient burning of liquid fuels. Primarily my work focuses on the study of various liquid atomization techniques employed in liquid propulsion systems using optical diagnostic tools. Development of theoretical/empirical models for spray characteristics as well as numerical simulations are also the part of the analysis. Development of solver for simulation of high enthalpy flows with real gas effects and non-equilibrium chemistry is also another area our group is interested in.
