Numerical calculation of radiative heat transfer from non-equilibrium, high-enthalpy shock layers generated around a blunt body has been performed. 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 layer generated immediately behind the shock wave. Accordingly, as upstream Mach number increases, the intensity of the radiative emission sharply increases, resulting in sharp increase in the radiative heat transfer. In this study, the thickness of the strong emission layer is almost independent of the nose radius. Hence, the radiative heat transfer is almost unchanged with the radius.
