Parallel computation of fully coupled strongly radiating hypersonic flowfield is attempted. A detailed multi-band model is employed in the radiation calculation. The radiative heat flux is obtained by first solving the radiative transfer equation along radiation rays, and then radiative intensities are summed over the solid angles. In order to reduce a vast computing time due to spectrally detailed multi-band calculation, a parallel computation is attempted in the calculation. The strategy in the parallel computation is to divide the wavelength range in the multi-band model into groups, and assign them to the available PEs. Calculations are carried out for the flowfield over an axisymmetric blunt body of 1.524m nose radius at a speed of 15.24 km/sec. It is shown that a converged solution for strongly radiating flowfield can be obtained within a feasible computing time.
