Title: Pressure gain combustion power plant analysis and cycle thermo economic optimization

The research is aimed at analyzing the concept of pressure gain combustion for its implementation in powerplants and performing their thermo-economic analysis for making PGC powerplants practically feasible. The research includes an assessment of cycle performance in simple and combined configuration to identify the most promising layout options, with key emphasis on power to gas solutions for adaptability to renewable and sustainable fuels. Critical challenges such as blade cooling will be studied for PGC and feasible solutions will be identified. Moreover, thermo-economic analysis will be carried out to optimize the cycle from the cost and operational perspective. The work will lead to the development of thermodynamic and cost models for PGC combustors. The resulting updated cost functions and optimized design parameters will be critical in overcoming technical and economic challenges for the development of efficient and environmentally friendly PGC powerplants.

Background:

Abhishek was born in Uttar Pradesh, India in 1991. He obtained his Bachelor's degree in Aerospace Engineering from Amity University, India in 2014 and his Master's degree in Aerospace Engineering from the Indian Institute of Technology Kanpur, India in 2017. During his masters, he developed and experimentally investigated the novel Reverse Flow Slinger combustor for high flame stability and low NOx emissions. Subsequently, he joined the Indian Institute of Science (IISc) Bangalore in 2018 as a Project Associate, where he investigated the performance of the high shear class of gas turbine injectors with laser-based optical diagnostics. At IISc, he also designed a high-pressure optically accessible gas turbine combustor rig and an optically accessible supercritical steam test loop. In January 2022, he joined DIME, University of Genova as a Marie Curie Early Stage Researcher under the INSPIRE ESR 13 Project, where he is working on the thermo-economic cycle optimization of the Pressure Gain Combustion powerplants.
