Title: Numerical modelling and optimization of cooling solutions for PGC concepts
Next generation Gas Turbine engines should be highly efficient with lesser carbon emissions. Pressure gain Combustion (PGC) technologies offer a promising solution to reach our future goal. Rotating Detonation Combustor (RDC) characterized as a Supersonic type PGC mainly involves detonation waves to increase the pressure gain. The main aim of this PhD is to design optimized cooling solutions for RDC engines such as to facilitate the engines of tomorrow.
Innovative state of the art non-conventional cooling configurations will be designed and optimized for higher efficiency and lesser pressure drop. Additive manufacturing techniques will be utilized to build the components, hence necessary changes in the computational models are to be accounted for the shift in wall roughness. Performance verification of the obtained design is performed by the means of high fidelity validated numerical models. The optimized design will be experimentally tested by ESR 11.

Planned secondments: ENSMA – 3 months, POLITO – 2 months, AVIO 1 month.
Background: I am an Aerospace Engineer, I have obtained a Master's degree in Aerospace Engineering from École Centrale de Lyon (ECL), France. Hailing from a small town called Ramanagara located in the southern part of India. I completed my Bachelor's in Aerospace Engineering from Jain University, situated in the outskirts of Bangalore. Where I learnt my most unforgettable lessons of CFD and combustion from my mentor Dr. Allamaprabhu C Y by involving in the ambitious project of designing a Gas Turbine Combustor. After my Bachelor's I was working as a Teaching Assistant in Jain University.
During my Masters in ECL the important concepts of Optimization and Aerospace principles were imbibed in me by my mentors. I had a wonderful opportunity to work on the LES of Laminar Separation Bubble (LSB) for low Reynolds number flows during my Master thesis in ENSTA ParisTech, the most interesting part was to learn how the size of the LSB effects the transition to turbulence. Currently I am working under the guidance of Professor Andreini for designing an optimized cooling system for PGC engines.
Personal interests: Computation Fluid Dynamics, Optimization, Combustion, Turbulence and Heat Transfer.
