Abstract

The experimental study was conducted on transpiration cooling in the free-piston shock tunnel HIEST. Under high-enthalpy and high-Reynolds number conditions, surface heat flux distributions on a flat plate were measured downstream of the C/C porous injector located 140 mm behind the plate leading edge. The test free-stream condition was varied; Stagnation enthalpy was 4 MJ/kg to 14 MJ/kg, the stagnation pressure 14MPa to 50MPa and free-stream Reynolds number was 0.8x10^6/m to 5x10^6/m. Changing the plenum chamber pressure for coolants, the flow-rate of gaseous helium and nitrogen was changed from 0g/s to 5g/s. The effects on surface heat flux of Reynolds number, enthalpy and coolants were discussed.
