Experimental study of the reverse flow in the forward separation region in a pulsating flow around a spiked body

Abstract:
The flow with a free-stream Mach number $\mathrm{M}_\infty=6$ around a cylindrical body with a sharp spike is studied. The existence of a supersonic reverse flow for one of the phases of the pulsating flow regime is experimentally validated. A range of spike lengths is determined, which ensures a region of a supersonic reverse flow near the side surface of the spike. The time of existence of the supersonic reverse flow region is shown to be $0.15$ of the period of pulsations if the spike length equals the model diameter.
Keywords:
supersonic flow, shock waves, self-sustained pulsations.
