Reynolds number effects in swept-shock-wave/turbulent-boundary-layer interaction

摘要

The interaction between a turbulent boundary layer and a glancing shock wave produced by a wedge is studied numerically and experimentally. The flows correspond to a nominal Mach number 2.5, two widely different Reynolds numbers, and a range of incidence angles giving both attached and separated flows. The Reynolds number effects on several flow features, including upstream influence, incipient separation, and inception length, are discussed. The computations are compared with the low-Reynolds-number experiments of Kubota and Stollery and also to some newly performed high-Reynolds-number experiments, and good agreement is achieved.
