SUMMARY

Having completed a bachelors from Manipal Institute of Technology and a Masters degree from Cranfield University, I’m now pursuing a PhD at Hallam. I’ve worked in the UAV design industry for 1.5 years. My hobbies include football, reading, trekking, cycling, travelling and visiting museums and historical places.

RESEARCH

This research aims to assess the effectiveness of transpiration cooling and its impact on hypersonic boundary layers.

By conducting Direct Numerical Simulations (DNS) on ARCHER2, we’ll analyse various injection configurations and shock wave effects. Our methodology involves utilizing the Shock Boundary Layer Interaction (SBLI) code, validated against experimental data, exploring different blowing configurations and geometric parameters, targeting laminar, transitional, and turbulent flows.

My ultimate goal is to optimize cooling efficiency while minimizing adverse aerodynamic effects. Planned validation studies include comparisons with prior research and experimental validation in a wind tunnel. This comprehensive approach will enhance understanding and potentially improve cooling strategies for hypersonic vehicles.
