Abstract
Radiative gas dynamics of a hydrogen laser-supported plasma generator and radiative heating of the internal surface of the plasma generator are studied numerically. For this purpose, a radiative gas dynamic model of the laser-supported wave in the cylindrical channel of the laser-supported plasma generator is created. The model is based on the Navier-Stokes equations, energy conservation equation for heat conducting gas in chemical equilibrium, and the radiation heat transfer equation using the multigroup spectral approximation. The numerical study is performed for the typical parameters of the laser-supported plasma generator: input velocities u 0 = 10-200 m/s, pressure p = 1 atm, and CW CO 2 laser radiation power P L = 100-200 kW.
