PhD project:

Title: PGC propulsion application with part load and dynamic analysis

Short description: The goal of this research work is to study the effects of gas dynamic phenomena in PGC at cycle level and to identify the operational limitations with regards to propulsion application. The effects of gas dynamic cross-interference and the resulting operational instabilities will be studied in order to develop an operational envelop for the PGC gas turbine. The research work would yield a full performance map at variable ambient conditions of a PGC simple cycle gas turbine, consisting of real processes, considering the unsteadiness and possible feedback loops in the gas turbine operation, optimized to get maximum thermodynamic efficiency and specific impulse, and minimum emission. The research would also result in the detailed description of the dynamic performance of the PGC cycle gas turbine and the development of control concepts for the engine.

Sreenath was born in Kerala, India in 1992. He obtained his Bachelors degree in Mechanical Engineering from University of Kerala, India in 2014 and his Masters degree in Aerospace Engineering with specialization in Aircraft Propulsion from Jain University, India in 2017. His Masters degree thesis was on the topic “Studies on Flow Instabilities due to Simulated Supercritical Rayleigh Heat Addition in an Afterburner”, and was done in collaboration with CSIR – National Aerospace Laboratories, India. In 2018, he joined the Centre for Airborne Systems, DRDO, India as a Research fellow in Mechanical & Aerodynamics division. He has worked on several projects involving ergonomic design & structural analysis of aircraft components, and CFD studies on wide body aircrafts for aerodynamics and ice accretion. In September 2021, he joined DIME, University of Genova, Italy, as a Marie Curie Early Stage Researcher under the INSPIRE Project.
