Abstract
Regimes of continuous spin detonation and continuous multifront detonation of a gas-droplet mixture of gaseous hydrogen and liquid oxygen in a plane-radial combustor (inner diameter of 100 mm and outer diameter of 300 or 200 mm) with exhaustion toward the periphery are obtained for the first time. The detonation front height of the gas-droplet mixture is greater than that of the gas mixture, which is caused by the critical size of detonation existence. Centrifugal forces acting on the products behind the detonation wave front favor faster filling of the plane-radial combustor with the fresh mixture and increase the detonation front height.
