“…In a shock tube, this is a reasonable assumption, because the initial boundary layer growth after shock passage is very small (Petersen and Hanson 2003). But in a wind tunnel flow, the shock will interact with the boundary layer developing over the window (Adamson and Messiter 1980). The interaction will likely smoothen the refractive index field locally, hence the optical distortions.…”

“…The shift in the height of the ridge of maximum wall-normal velocity fluctuations seems to correlate well with the taller PIV bubble. It is unclear why the experimental bubble is taller, but one can speculate this to be related to the presence of the wind-tunnel side walls, which tend to enhance the size of the separation bubble 3 . However, note that the contourmap indicates a good match for the shock-system position, suggesting that the size of the interaction found by the LES is in good agreement with the experiment.…”

“…The two-dimensional interactions most commonly studied are the interaction of a normal/oblique shock wave with a laminar/turbulent flat plate boundary layer and the case of a flow over a bump or over a compression corner. A review of the aforementioned interactions can be found in Adamson and Messiter [3]. The case of an incident oblique shock is historically the least well studied, and is the case on which we focus our attention.…”

The need for better understanding of the low-frequency unsteadiness observed in shock wave/turbulent boundary layer interactions has been driving research in this area for several decades. We present here a large-eddy simulation investigation of the interaction between an impinging oblique shock and a Mach 2.3 turbulent boundary layer. Contrary to past large-eddy simulation investigations on shock/turbulent boundary layer interactions, we have used an inflow technique which does not introduce any energetically-significant low frequencies into the domain, hence avoiding possible interference with the shock/boundary layer interaction system. The large-eddy simulation has been run for much longer times than previous computational studies making a Fourier analysis of the low frequency possible. The broadband and energetic low-frequency component found in the interaction is in excellent agreement with the experimental findings. Furthermore, a linear stability analysis of the mean flow was performed and a stationary unstable global mode was found. The long-run large-eddy simulation data were analyzed and a phase change in the wall pressure fluctuations was found to coincide with the global-mode structure, leading to a possible driving mechanism for the observed low-frequency motions.Keywords shock boundary layer interaction · global mode · compressible turbulence · LES · low-frequency unsteadiness · separation bubble · digital filter · inflow turbulence PACS 47.40.Nm · 47.40.Ki · 47.27.ep

“…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).…”

Three-dimensional instantaneous structure of a shock wave/turbulent boundary layer interaction

et al. 2009

View full text Add to dashboard Cite

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.
