Abstract: The results of a systematic study of the structures and flow regimes with an oblique detonation wave (ODW) in supersonic reacting flow have been presented. The main task is to clarify the conditions for the stationarity of the forming shock wave − detonation structures. This paper presents the main results of numerical studies of two-dimensional supersonic flows with ODW, formed by compression bodies in the form of: a) a flat wedge, b) a ―wedge-flat body‖ combination, c) a wedge above a solid surface, and d) in the form of a single-pass solid spiral in the gap between the walls of two coaxial cylinders (two-dimensional approximation). For all the considered reacting mixtures and variants of the compression body, the phenomenon of a double solution (bifurcation of a stationary solution with respect to the 1starting conditions for the detonation chamber operation) was found, i.e. after completion of the transition process, the final stationary shock-detonation structure depends on the initial state of the flow in computational domain at the initial moment t=0.
