Abstract
A numerical method for calculating a strongly radiating axisymmetric flowfield is developed. Radiative transfer is treated one, two, and three dimensionally. Radiative heat flux is evaluated using a model developed earlier that combines Planck, Rosseland, and gray-gas models. The flow solution is obtained with a fully implicit time-marching method using a full block matrix inversion. To show its robustness the method is applied to calculate the environment of a blunt body flying at the velocity of 16 km/s. The results show that the multidimensional radiative transport calculation is different from the one-dimensional calculation. The computational costs for the method are given for each method of radiative transfer calculations. The method is also tested for an experiment conducted in a ballistic range. The calculated radiative heat flux values are lower than the measured value by a factor of at least four.
