Abstract

Parallel computation of fully-coupled strongly radiating hypersonic flowfield is carried out. A detailed multi-band model is used in the radiation calculation, and the radiative heat flux is calculated using ID (tangent-slab) or 2D approximations in radiative transfer, or considering 3D radiative transfer directly. In order to reduce a vast computing time due to a spectrally detailed and multi-dimensional radiation calculation, parallel computation is employed. The strategy in the parallel implementation of the code is to decompose the wavelength range in the multiband model into groups and assign them to the available number of processors, instead of decomposing the computational domain. Calculations are carried out for the flowfield over an axisymmetric blunt body of 1.524 m nose radius at a speed of 15.24 km/s. The converged solutions for strongly radiating flowfield can be obtained within a feasible computing time.
