Analysis of unsteady behaviour in shockwave turbulent boundary layer interaction (2012, result): “A Strouhal number StL = fL/U∞ can be defined, where L is the length of the mean separation bubble (L = 6.0δ0 in the present LES), and gives StL = 0.0234 which is consistent with the range of StL indicated by Dussauge et al. (2006).”
Stability, Receptivity, and Sensitivity Analyses of Buffeting Transonic Flow over a Profile (2015, background): “However, besides the shock unsteadiness, a shock-wave/boundarylayer interaction (SWBLI) may present medium-frequency unsteadiness caused by the separated zone: it is well established [12] that the”
Direct numerical simulation of supersonic turbulent boundary layer over a compression ramp (2007, background): “Dussauge et al. [17] compiled frequencies that were found in experiments for different configurations and found that the dimensionless frequency of the shock motion is mainly between 0.02 and 0.05.”
Some physical aspects of shock wave/boundary layer interactions (2009, background): “Fig. 19 Dominant frequency in supersonic shock/boundary layer interactions (from [ 26 ])”
Analysis of shock motion in shockwave and turbulent boundary layer interaction using direct numerical simulation data (2007, methodology): “The fact that the Strouhal number of the low-frequency shock motion defined using the mean separation bubble length lies in the experimental range (Dussauge et al. 2006) also supports this argument. Pirozzoli & Grasso (2006) performed a DNS of a reflected shock interaction and proposed that the shoc”
A simple model for low-frequency unsteadiness in shock-induced separation (2009, methodology): “Application of the model to several experiments of shock-induced separation Dussauge et al. (2006) proposed a compilation of the Strouhal number SL for several data for separated flows available in the literature for Mach numbers ranging from 0 to 5, for compression ramps and shock reflection flows.”
A scaling analysis for turbulent shock-wave/boundary-layer interactions (2013, background): “For example, a dimensionless frequency of the separation shock oscillations can be defined with a nearly constant value, for any shock-induced separation considered (see Erengil & Dolling 1991b; Dussauge et al. 2006).”
Low-frequency dynamics of shock-induced separation in a compression ramp interaction (2009, result): “This assumption is based on the results from previous studies that show that wall-pressure fluctuations and mass-flux fluctuations possess significantly higher energy content in the dominant frequency range (see Dussauge et al. 2006; it is also seen from the pressure fluctuations in figure 1).”
Unsteady effects of strong shock-wave/boundary-layer interaction at high Reynolds number (2017, background): “04, consistent with experimental values found by Dussauge et al. (2006) for different flow geometries and upstream conditions.”
