“…A vast body of research has therefore been accumulated over the years describing the interaction's most salient features. Reviews of much of the early work, concerning two-dimensional interactions, may be found in Green (1970), Hankey & Holden (1975), and Adamson & Messiter (1980). More recent reviews, with emphasis on the unsteadiness properties, including three-dimensional interactions, may be found in Délery & Marvin (1986), Dolling (2001), and Smits & Dussauge (2006).…”

An experimental study is carried out to investigate the three-dimensional instantaneous structure of an incident shock wave/turbulent boundary layer interaction at Mach 2.1 using tomographic particle image velocimetry. Large-scale coherent motions within the incoming boundary layer are observed, in the form of three-dimensional streamwise-elongated regions of relatively low-and high-speed fluid, similar to what has been reported in other supersonic boundary layers. Three-dimensional vortical structures are found to be associated with the low-speed regions, in a way that can be explained by the hairpin packet model. The instantaneous reflected shock wave pattern is observed to conform to the low-and high-speed regions as they enter the interaction, and its organization may be qualitatively decomposed into streamwise translation and spanwise rippling patterns, in agreement with what has been observed in direct numerical simulations. The results are used to construct a conceptual model of the three-dimensional unsteady flow organization of the interaction.

“…Studies mapping the mean flow properties as functions of Mach number and Reynolds number, as well as the incident shock wave strength and state of the incoming boundary layer have been conducted (e.g. Holder et al 1955;Chapman et al 1958;Green 1970). The unsteadiness properties of this type of interaction, however, have been less well documented.…”

Particle image velocimetry measurements of a shock wave/turbulent boundary layer interaction

Particle image velocimetry is used to investigate the interaction between an incident shock wave and a turbulent boundary layer at Mach 2.1. A particle response assessment establishes the fidelity of the tracer particles.The undisturbed boundary layer is characterized in detail. The mean velocity field of the interaction shows the incident and reflected shock wave pattern, as well as the boundary layer distortion. Significant reversed flow is measured instantaneously, although, on average no reversed flow is observed. The interaction instantaneously exhibits a multi-layered structure, namely, a high-velocity outer region and a low-velocity inner region. Flow turbulence shows the highest intensity in the region beneath the impingement of the incident shock wave. The turbulent fluctuations are found to be highly anisotropic, with the streamwise component dominating. A distinct streamwiseoriented region of relatively large kinematic Reynolds shear stress magnitude appears within the lower half of the redeveloping boundary layer. Boundary layer recovery towards initial equilibrium conditions appears to be a gradual process.

“…Other parameters that do show the desired behavior with respect to a. and M^ are, for example, (M n -l)/Moo, (p r -IJ/Moo, and A = (Moo/M 2 -1), a parameter used successfully in two-dimensional impinging shock interactions. 23 The reason these parameters can be used is, once again, that they are weak functions of M^ (at least for the Mach number range of the present study).…”
