    Liquid Propulsion System Center, Indian Space Research Organization (ISRO) Department of Space (Trivandrum, INDIA)



    Working in the Propulsion Research & Studies Group at ISRO. The focus of my job is to provide the engineering solutions to troubleshoot problems in the Flow and Thermal area for development of liquid & cryogenic rocket stages, engines and facilities with the help of thermal and CFD simulation.



    Performed two-phase CFD analysis of tank draining to determine liquid interface motion and ullage pressure-temperature evolution using Volume of Fluid technique including mass transfer mechanism.

    Developed a conjugate CFD model for simultaneous operation of clustered 800 N thrusters for detailed study of under expanded plume behavior, plume impingement, interaction including gas radiation using Discrete Ordinate Methodology. The complex phenomenon of multiple plume interactions, shear layer development, plume radiation and flow reversal was well captured.

    Three dimensional flow and thermal analysis of Air heater unit for scramjet propulsion test facility. CFD modeling for different configurations of secondary air injection was performed to determine uniformity in mixture composition and temperature at heater module outlet.

    Performed transient simulation of rocket engine start up and shut down in vacuum, in order to determine safe mode of operation for high altitude test facility.

    Performed detailed two phase analysis (both Lagrangian & Eulerian dispersed phase treatment) to design water cooled deflector pit for rocket engine testing in ground. Carried out experiments for concept verification & CFD code validation at sub-scale level for plume impingement on inclined plate with multiple water orifices.

    Completed CFD simulation of transcritical methane flow in rocket engine regenerative channels and combustion modeling of single element pre-burner injector to understand flow/flame field and combustion characteristics at supercritical conditions.

    Performed multi-phase, multi-species simulation for spray cooing of combustion gas with water liquid to predict thermal profile over gas generator walls for thermostructural analysis. Complex two phase physics and mass transfer phenomenon modeled in eulerian framework.

    Developed a transient CFD model to determine GN2 pressure and temperature evolution in LH2 tank to further validate with the flight data.

    Carried out three dimensional conjugate CFD analysis to simulate hot test of twin nozzle configuration liquid rocket stage to determine the nozzle wall temperature due to entrainment and surface radiation effects.
