Numerical analyses have been conducted on radiative heat transfer from hypersonic, non-equilibrium air shock layers over a reentry body. The band method developed here enables one to conduct wavelength-dependent, three-dimensional radiative transfer calculation in which self-absorption effect is taken into account. The radiative heat transfer calculated here was found comparable with convective one. Atomic species and N2+ were found to be dominant radiators. Electrons play an essential role in

At a high Mach number, since electron density is at a high level, another peak appears near the wall, thereby enhancing the radiative heat transfer at the stagnation point and enlarging the half-width of the radiative heat flux to the wall.
