A method based on the use of quasi-gasdynamic equations is developed for calculating the high-altitude jets flowing into a rarefied gas. The equations of continuity of the gas mixture components and the transport equations for vibrational energies in a quasi-gasdynamic formulation are obtained from the Boltzmann equation. It was shown that when calculating with the use of quasigasdynamic equations, the radiation intensity of high-altitude jets is significantly lower than when calculating based on the standard system of Navier-Stokes equations. The calculation results are compared with the available experimental data.
