Study of vibrationally nonequilibrium expansion of a CO2N2H2O mixture
Abstract
The optimal value of the population inversion for the 00(0)1 and 10(0)0 levels of the CO2 molecule formed during supersonic expansion of CO2N2H2O gas mixtures in a nozzle is calculated in two stages. First the vibrationally nonequilibrium expansion is computed for various relations of the components and values of temperature and stagnation pressure. Then these results are put in the form of nomograms of smoothed points. This enables one to find rapidly the maximum possible value of population inversion or gain coefficient and to study the variations of these functions with various parameters.
