Abstract
The paper reports results of numerical simulations of flow structures with oblique detonation waves that arise in supersonic flow of a uniformly mixed mixture of hydrogen with air over two–dimensional compression surfaces (wedge and cone). In the first series of calculations, the internal structure of the detonation front was not resolved but the physical processes in the remaining flow region were simulated with allowance for nonequilibrium chemical reactions. This flow is shown to have a complex wave structure, and the dependence of this structure on the parameters of the problem is studied. In the second series of calculations, nonstationary wave structures at the detonation front were obtained. These nonstationary waves are compared with the structure of the spin head in a nonstationary spin detonation.
