Abstract
A numerical solution was provided for the problem of three-dimensional unsteady flow of a propane-air mixture with continuously rotating detonation waves in an annular channel between a flat disk and a ring. Critical values of the channel width and the ring inner diameter were determined, limiting the range of their values at which rotating detonation occurs as a result of direct initiation. Computational data were obtained characterizing the dependence of the gas-dynamic flow parameters and integral force characteristics on the channel width and the ring inner diameter.
