A numerical method for calculating a strongly radiating axisymmetric flow field is developed. Radiative heat flux is determined one-, two-, and three-dimensionally using a model developed earlier which 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. The method is applied for calculating the environments of a blunt body flying up to the velocity of 16 km/s. The calculated results are compared with the experimental data conducted in a ballistic range. The results show the calculated radiative heat; flux values are lower than the measured value by a factor of about five. The possible reasons for these discrepancies are given.
