| Abstract: | Experimental and numerical simulation for a 42 degree compression corner were taken to study the mechanism of the unsteady high heat flux at Mach number 5. The test results indicate that there is strong shock wave interaction and sweeping dynamically in the flow field，the numerical simulation results show that shock wave transition from regular reflection to Mach reflection with the increase of separation shock angle, then complex shock wave system forms and normal shock moves relative to the wall, behind which the wall temperature rises to 5 times of the temperature of free stream and 90 times of the pressure. Keeping the angle of the separation shock wave constant and changing the Mach number will also lead to the transition of shock wave reflection and the location of peak temperature and pressure moves from first wedge to the second. So complex shock wave has important influence on heating effect. |
