About Me: I work in the research fields highlighted in the research interest section. Currently, my research focus is on improving burner design of coal-fired reactors with cost-effective retrofitting to optimize pollutant emissions from ammonia-coal co-firing. I defended my PhD thesis at IIT Delhi in the January of 2023 in which I worked on resolving the coupled interactions between flow field and combustion inside entrained flow coal reactors. Along with my PhD thesis work, I also worked on a DST project to develop a pressurized drop tube reactor to measure the high-pressure kinetics of Indian coal blends. It is a first of its kind facility developed in India installed at IIT Delhi. For more details about me please visit my CV.
Research Interest: Turbulent combustion, Dynamics of reacting and non-reacting flows, Numerical modeling of entrained flow reactors, Resolving coherent structures in turbulent flows, Gasification, Ammonia co-combustion, Large-eddy simulations.
