ON MOLECULAR VIBRATIONAL RELAXATION IN THE FLOW OF A CHEMICALLY REACTING GAS
Abstract
A method is presented for predicting the molecular vibrational temperature in a gas flow where the internal energy of vibration is small compared to the total internal energy of the gas. Coupling between the relaxation rate of molecular vibration and atomic recombination is neglected. The results of calculations suggest that large differences between the vibrational temperature and the random translational temperature of an oxygen-like gas can occur in certain flow configurations such as the flow of a chemically reacting gas through a hypersonic nozzle. A criterion is proposed which determines the position in the flow at which significant departures from vibrational equilibrium are likely to occur. (Author)
