Current research interests:

•Atomization and combustion of conventional and novel propellants

•Optical diagnostics of multiphase and reacting flow

•Computational analysis of high enthalpy flows with real gas effects

•CFD studies of fuel injection and mixing of supercritical/trans critical fluids like LOx

•Sloshing and phase change analysis of cryogenic propellants in microgravity

•Aerosol generation of non-Newtonian liquids from expiratory events like coughing and sneezing

Future Research:

•Combustion of gel propellants (shear-thinning liquids) for rocket applications

•Propellant migration in a microgravity environment for spacecraft application

•Combustion in supercritical state in the context of cryogenic engines

Institutional Research

• Effect of acoustic fluctuations on unsteady sprays for semi-cryogenic engines (for ISRO)

Forcing frequency (ff) and natural frequency (fn) are present in the spectrum

Harmonics of fn are observed

Linear combinations of ff and fn (a ff  + b  fn ,where a and b are integers) are present 

Indicates quasiperiodicity in self-oscillatory system
