Abstract

The prompt oblique detonation waves (ODWs) induced by finite-length wedges are investigated by numerical simulations. The numerical results show that premature ignition resulting from the initial conditions can result in the formation of the prompt ODWs that cannot take place spontaneously over the wedges. The fully coupled and the partially coupled prompt ODWs are observed in the flow field. The partially coupled prompt ODW is unstable; it will be destabilized by the local explosion resulting from the unstable combustion wave.
