Aerodynamic heating poses a huge problem as flight speeds cross the sonic barrier. Hypersonic flights are getting a lot of attention in modern-day research and ways to deal with the high thermal stresses due to aerodynamic heating is being studied. One way to reduce this is by making use of the fuel onboard as a heat sink to absorb heat from the structural components of the aircraft. In doing so, the fuel itself starts heating up and reaches a supercritical state. Liquids at supercritical states become gas like without having to go through atomization or evaporation. Injecting supercritical fuels into supersonic crossflow to investigate the effects of liquid fuel in supercritical state is the main objective of this study. The fuel investigated in this study is JET A1 or kerosene. The transition of liquid fuel to gaseous state supercritically is found to increase mixing efficiency, which will be studied in this work. Flow visualization techniques will be performed to better understand the flow properties post-injection for various injection conditions.
