Abstract：An approximate collision-radiative method is developed to calculate energy level populations of atoms and applied to simulate radiative transfer in a shock layer. Considering nonequilibrium plasmas with the electronic temperature below 20000 K, we introduce correction factors to the Saha–Boltzmann equation and simplify the master equation of the full collision-radiative model. Based on the method, the error of heat flux is smaller than 5% in a two-cell problem and smaller than 7% in the Stardust re-entry flow field compared with the correlated-k method. Furthermore, almost a factor of 2 is obtained in the improvement of computational efficiency compared with the nonequilibrium air radiation (NEQAIR) code. The results show that the present method is reliable and efficient.
