This research aims to understand the impact of shock wave-boundary layer interaction on flow separation characteristics for supersonic vehicles.
Employs direct numerical simulation to analyze laminar boundary layer behavior under varying shock intensities and wall temperatures.
Focuses on predicting the dimensions of the flow separation zone using an optimized formula based on the Katzer prediction formula.
Increased shock intensity leads to the formation of a secondary separation zone, affecting the primary separation zone's pressure gradient and size.
The optimized prediction formula demonstrates high accuracy for primary separation zone dimensions across Mach number 1.6–15 and wall temperatures from 0.2–1.
