Detonation Stabilization in Supersonic Flow: Effects of Suction Boundaries

What is it about?

In the present work, detonation stabilization in the supersonic flow initiated with two symmetrical hot jets, is numerically investigated in the straight channel with suction boundaries. When the suction slots are turned on, the overdriven detonation undergoes a gradual attenuation along with the weakening of the transverse waves, hence leading to dynamic detonation stabilization in the supersonic flow associated with irregular pressure oscillations. When the suction slots are closer to the detonation front, the forward propagation of the detonation in the supersonic flow can be more effectively prohibited, implying that the suction slots should be distributed as close as possible to the detonation front in order to realize the maximal suction effect using the minimal suction slots.
