N2 - Radiative heating of internal surface of the hydrogen Laser Supported Plasma Generator (LSPG) is studied numerically. For this purpose the Radiative Gas Dynamic (RGD) model of Laser Supported Wave (LSW) in cylindrical channel of LSPG is created. The model is based on the Navier-Stokes equations, energy conservation equation for chemically equilibrium heat conducting gas, and radiation heat transfer equation in multi-group spectral approximation. Numerical study is performed for the following parameters of LSPG: input velocities u0=10-200 m/s, pressure p=1 atm, powerful of the CW CO2 laser radiation PL=100 kW. Group and integral radiation heat fluxes on internal surface of the LSPG cylindrical channel of length L=11 cm at radius R=2 cm were calculated by the P1-approximation of the Spherical Harmonics method, the Discrete Directions method, and the Discrete Ordinates method. Numerical simulation results are compared. Recommendations for using each of the methods for the problem under consideration are presented.
