| Research Abstract |
Radiative heat transfer from non-equilibrium, high-enthalpy shock layrs generated around a blunt body has been studied. At Mach numbers from 25 to 35, the radiative heat transfer is mainly caused by strong radiative emission in a thermally and chemically non-equilibrium layr generated immediately behind the shock wave. According as an upstream Mach number increase, the intensity of the radiative emission sharply increases, resulting in sharp increase in the radiativeheat transfer. Under the above-mentioned condition, the thickness of the strong emission layr is almost independent of the nose radius. Hence, the radiative heat transfer is almost unchanged with the radius at such a low Mach number levels. At higher Mach number levels, radiative emission from a high-electron-density region near the wall become dominant. In this case, the radiative heat transfer increases with the dimensions of the body.
