Abstract
The method has been developed to calculate infrared radiation of vibrational nonequilibrium gas based on k-distribution. A comparison
of the data on the calculated nonequilibrium radiation with results of other
authors and with experimental data has shown satisfactory agreement. It is
shown that the results of calculation of radiation intensity using
nonequilibrium and equilibrium methods significantly differ from each other.
The discrepancy increases with increasing height (decreasing pressure) and can
exceed an order of magnitude.
