The nature of the flow of a dissociating diatomic gas in a convergent-divergent supersonic nozzle is investigated by measuring the distribution of flow parameters along the nozzle. Two parameters are measured, namely the degree of dissociation and the static pressure. The degree of dissociation is measured by a spectroscopic method. The pressure is measured by [xcup ]-tube manometers. The results are compared with Bray's (1959) theory and Logan's (1957) prediction.
