Abstract A 3D numerical model of a combustion chamber with continuous rotating detonation wave was performed. The ignition, onset and stabilization of a rotating detonation wave in combustion chambers of different shapes was investigated. The effect of additional oxygen injection on the onset of rotating detonation wave was studied. Formation of a stable detonation wave was investigated against different factors: internal body diameter, injectors number and diameter, pressure at the fuel and oxidizer orifices. The calculations were performed using specialized computer code designed by the Authors at the APK-5 super-computer system.
Highlights The process of switching to a rotating detonation wave mode was investigated. The process of detonation wave stabilization with additional oxygen is considered. Different fuel concentrations are considered. The processes in combustion chambers of various sizes are considered. The influence of the chamber width on the detonation wave is studied.
