Three-dimensional modeling of rotating detonation in a ramjet engine

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.
