Abstract:

Self-similar solutions of Van Dykes small-disturbance equations of hypersonic flow are found for a diatomic dissociating gas. The gas is characterized in a thermodynamically consistent way by an equation of state that is shown to be a good approximation, valid over a considerable range of degrees of dissociation and densities, to Lighthills ideal dissociating gas. As in the analogous case for a perfect gas, a shock appears whose coordinates satisfy a power law. Results are obtained for two-dimensional and axisymmetric flows. A comparison with the corresponding solutions for a perfect gas shows qualitatively similar behavior, although there are significant quantitative differences. Author
