Investigation on Compressible Ramp Flows
並列摘要
An experimental study on the compressible ramp was conducted. The mean surface pressure distributions indicate the upstream movement of the detached shock with increasing ramp angle at Mach 1.28. The subsonic ramp flows at Mach 0.64 and 0.83 show the strong inviscid-viscous interactions. The upstream compression can be scaled with the similarity parameter Mα, and the upstream and downstream pressure gradients are associated with the ramp angle and quadratic function of the freestream Mach number. The analysis of surface pressure fluctuations for all the test cases indicates that the presence of a ramp has a minor effect on the unsteadiness of the flows.
