SIMILITUDE REQUIREMENTS FOR A DISSOCIATING DIATOMIC GAS.
Abstract
The flow of a dissociating diatomic gas behind a strong shock wave is examined and a parameter for the scaling of the length of the non-equilibrium region is obtained. The dissociation similarity parameter is verified for nitrogen by comparing it with the results of numerical integrations of the equations of motion and the dissociation rate equation behind a strong shock wave. A relationship between the temperature in the dissociation region and the degree of dissociation is obtained for the flow behind a strong shock wave. This relationship is simplified and the resulting approximation is shown to be good within 10 per cent. An expression relating the temperature to the distance through the dissociation region was obtained for nitrogen. This relation, which is empirical in nature, gives a method for rapidly calculating the temperature profiles through the dissociation region behind a strong shock wave in nitrogen. (Author)
