Mr. Ajay Kumar Jaiswal

Ph.D Research Scholar

Brief Bio:Mr. Ajay Kumar Jaiswal is a PhD scholar under the guidance of Dr. Pallab Sinha Mahapatra. He received his M.Tech (Fluids Engineering) and B.Tech (Mechanical Engineering) from Motilal Nehru National Institute of Technology Allahabad and Sharda Group of Institutions in 2017 and 2014, respectively. His research interests include (not limited to) blade cooling, heat transfer, microchannel and computational fluid dynamics.

About Research

I am working in the area of turbine blade cooling using microchannel. I am studying the influence of microchannel-based cooling on combined impingement and film cooling numerically and experimentally. The first goal of adopting a microchannel is to lower the thermal gradient that exists in traditional cooling approaches like impingement and film cooling, and the second goal is to improve cooling performance by bringing the coolant closer to the outer target surface. I am also investigating mist-air performance on microchannel embedded film cooled plates, both flat and curved. Water droplets added to the coolant will improve the cooling performance. Because water droplets absorb heat during evaporation, they serve as a discrete heat sink, allowing heated mainstream gases to cool even more. As a result of the substantially cooler air, which cools the material to a larger degree, the film cooling effectiveness increases.
