Announcing the Final Examination of Manoj Prabakar Sargunaraj for the degree of Doctor of Philosophy
The research methodology involves an exploration of effective cooling methods for the front edges of hypersonic vehicles, with a specific emphasis on the application of Supercritical CO2 (sCO2) in multiple jets for cooling. Numerical simulations are utilized to comprehend airflow patterns and heat transfer dynamics, particularly in extreme hypersonic conditions. Additionally, the study investigates the impact of varying Mach numbers, the utilization of specialized coatings, adjustments in jet angles and distances, and the potential of sCO2 as a coolant. A noteworthy finding is the capacity of sCO2 to convert absorbed heat into usable power, which holds significant promise for enhancing the overall performance of hypersonic vehicles. This research's uniqueness lies in its comprehensive consideration of multiple factors, including various cooling methods and structural aspects, contributing to a better understanding of how to optimize hypersonic vehicles for extreme conditions. The insights gained have the potential to advance the design and functionality of hypersonic vehicles and related systems.
