Keywords: heat protection; slot and uniform gas injection; hydrogen combustion; hypersonic flows
Slot and uniform intensive injections of air, helium and hydrogen from blunt-body surface into viscous shock layers are studied by various numerical and experimental methods. The results indicate that the most effective cooling of the probe surface occurs at moderate uniform injections and moderate Reynolds numbers.
