Visualization of shock structures from supersonic gas jet

Shocks are observed in the flow field of supersonic flows. Typically, in supersonic gas jets, shocks and expansion waves form diamond-like structures, also called shock diamond. In the shock diamond, different types of shock are present. The structures of these shock and expansion waves can be visualized through the schlieren technique. The flow field development of a supersonic gas jet is visualized with the schlieren technique in the following video. The objective of the experiment is to measure the distance of the first Mach disk from the nozzle exit at different exit Mach numbers and pressure ratios of the jet.

Supersonic flow past nose cone

The study of supersonic flow at Mach 1.7 over a nose cone involves analyzing the evolution and interaction of various shock waves. These shock waves affect the pressure and velocity profiles on the nose cone's surface, which are crucial for predicting its aerodynamic behavior. Additionally, the thermal profile on the cone's surface must be examined to assess the heat distribution and its impact on the cone's performance during high-speed flight
