Analysis of unsteady behaviour in shockwave turbulent boundary layer interaction (2012, background): “This behaviour is in good agreement with results reported by Dupont et al. (2006).”
Confinement effects in shock wave/turbulent boundary layer interactions through wall-modelled large-eddy simulations (2014, methodology): “In the STBLI experiments by Dupont et al. (2005, 2006), Piponniau (2009), Piponniau et al. (2009) and Souverein et al. (2010), regular shock intersections occurred for even the strongest interaction, which is replicated in the WMLES presented in the Appendix.”
Effects of micro-ramps on a shock wave/turbulent boundary layer interaction (2009, background): “[4] in their incident SWTBLI study at Mach 2.”
A simple model for low-frequency unsteadiness in shock-induced separation (2009, methodology): “Dupont et al. (2006) compared the longitudinal evolution of the wall pressure power spectral density (PSD) in an incident shock wave interaction as well as in a compression ramp interaction, with subsonic separated flows.”
A scaling analysis for turbulent shock-wave/boundary-layer interactions (2013, background): “…numerical studies performed at low Reynolds numbers (Reθ ' 5 × 103) indicate that the low-frequency shock motions are related to the dynamics of the separated bubble which forms downstream of the separation shock (Dupont et al. 2006; Touber & Sandham 2008; Wu & Martin 2008; Piponniau et al. 2009).”
Low-frequency dynamics in a shock-induced separated flow (2016, background): “As shown by Dupont et al. (2006), the shear layer shares many of the characteristics found in canonical plane mixing layers and incompressible shear layers.”
Low-order stochastic modelling of low-frequency motions in reflected shock-wave/boundary-layer interactions (2011, background): “In Dupont et al. (2006), the wedge angle varies from 7◦ to 9.5◦. In the LES, only the 8◦ case will be considered, as it is reported to be unsteady with an interaction length smaller than the 9.5◦ case, reducing the computational cost. In this paper, the interaction length L is defined as the distanc”
Three-dimensional instantaneous structure of a shock wave/turbulent boundary layer interaction (2009, background): “Overall, these results are consistent with the observations made by Dupont et al. (2006) in their incident SWTBLI, who recorded hot-wire signals and wall pressure fluctuations simultaneously at the reflected shock wave’s mean position, and were able to deduce that the reflected shock wave’s length…”
Flow physics and RANS modelling of oblique shock/turbulent boundary layer interaction (2013, methodology): “In regard to the scaling argument given by Pirozzoli & Bernardini (2011), it should be noted that the proportionality described by Dupont et al. (2006) was based on an experimental study in which the interaction parameter P was varied by changing the wedge angle – not by varying Reynolds number.”
Analysis of shock motion in shockwave and turbulent boundary layer interaction using direct numerical simulation data (2007, background): “Dussauge et al. (2006) suggested that the three-dimensional nature of the interaction in the reflected shock configuration is a key to understanding the shock unsteadiness. Ganapathisubramani, Clemens & Dolling (2007a) proposed that very long alternating structures of uniform low- and high-speed flu”
Low-frequency unsteadiness in shock wave–turbulent boundary layer interaction (2012, methodology): “STBLIs are of engineering interest and an important factor in vehicle development since large-scale unsteady flow separation can occur in the interaction, which deteriorates the quality of the flow downstream, and since the interaction can cause strong fluctuations of pressure and heat transfer at…”
Large-eddy simulation of low-frequency unsteadiness in a turbulent shock-induced separation bubble (2009, methodology): “3 turbulent boundary layer with a Reynolds number of about 2× 104 (based on the displacement thickness), consistent with the experiments performed at IUSTI [13, 11].”
Some physical aspects of shock wave/boundary layer interactions (2009, background): “As noticed in [28] and recalled by [12], a velocity scale”
Unsteady effects of strong shock-wave/boundary-layer interaction at high Reynolds number (2017, background): “This position apparently coincides with the reattaching shear layer, see figure 6(a), for which a characteristic frequency of the reattaching large-scale vortices is usually found around 0.5U0/Lsep (Dupont et al. 2006).”
