Abstract
In this study, operating conditions of a rotating detonation engine with internal mixing has been studied. Hydrogen and oxygen are supplied separately from gas storage tanks and mixed in an annular combustion chamber. The mixture is initiated by a spark discharge placed at the chamber wall surface. As a result, a strong deflagration after ignition is initially generated in the combustion chamber. The experimental results show that the following stages are involved to achieve stable propagation of the rotating detonation : i) a deflagration wave moves to the downstream, ii) a DDT process occurs in the downstream, iii) a detonation wave propagates in the upstream direction, iv) a rotating detonation is stabilized in the combustion chamber.
