Properties of Wall Pressure Fluctuations in a Separated Flow over a Compression Ramp

  • Conference paper
Turbulent Shear-Layer/Shock-Wave Interactions

Part of the book series: International Union of Theoretical and Applied Mechanics ((MANUTECH))

Summary

An experimental study of the unsteadiness of a shock/ boundary layer interaction is presented. The interaction is produced by a 24° compression ramp at Mach number 2.84. Multi-channel measurements of wall pressure fluctuations are performed. It is found that the shock has significant large scale “rippling”; the shock induced fluctuations produce a maximum in the space time correlation for negative time delay, indicating a strong modification of transport properties in the interaction. At last, the analysis of frequency measurements suggests that shock oscillation could be triggered by the bursting mechanism in the incoming boundary layer.
