• Three-dimensional instantaneous structure of a shock wave/turbulent boundary layer interaction (2009, result): “Such a conclusion is also consistent with the results obtained by Beresh et al. (2002) in their compression ramp interaction, who carried out a conditional analysis on planar PIV data in the streamwise–wall-normal plane, and found that positive fluctuations within the incoming boundary layer corresp”
• Effects of micro-ramps on a shock wave/turbulent boundary layer interaction (2009, background): “Several studies have forwarded a model based on experimental observations in which the low-frequency component of the unsteadiness is driven by large-scale variations in the streamwise velocity of the incoming boundary layer (see, e.g., [ 5 ,7]).”
• Effects of upstream boundary layer on the unsteadiness of shock-induced separation (2006, background): “However, unlike the results from Beresh et al. (2002), Hou et al. (2003) also showed that there is a clear correlation between thickening and thinning of the upstream boundary layer and the shock foot motion.”
• Low-frequency dynamics of shock-induced separation in a compression ramp interaction (2009, result): “This finding is consistent with the conclusions of Beresh et al. (2002), where the motion of the shock foot was found to be correlated with the velocity fluctuations in the upstream boundary layer.”
• Large-eddy simulation of low-frequency unsteadiness in a turbulent shock-induced separation bubble (2009, background): “Yet, it should be noted that it is uncertain whether such long events are caused by an experimental artifact (such as Görtler-like vortices formed in the expansion section of the wind-tunnel nozzle [5]).”
• Analysis of shock motion in shockwave and turbulent boundary layer interaction using direct numerical simulation data (2007, result): “This is in agreement with the experiments of Beresh et al. (2002) for a 28◦ compression ramp with M = 5, where the difference in the conditionally averaged mean velocity was roughly 2%.”
• Low-Frequency Unsteadiness of Shock Wave/Turbulent Boundary Layer Interactions (2014, methodology): “Beresh et al. (2002) sought to test Ünalmis & Dolling’s (1994) thickening/thinning mechanism by acquiring velocity data using the particle image velocimetry (PIV) technique in the upstream boundary layer together with simultaneous wall-pressure data under the intermittent region to infer the…”
