Low-order stochastic modelling of low-frequency motions in reflected shock-wave/boundary-layer interactions (2011, background): “…streaks, as for instance evidenced by the tomographic particle image velocimetry study of Humble et al. (2009), the success of the mechanism studied by Ganapathisubramani et al. (2009) in explaining the low-frequency shock motions depends on the existence of sufficiently long streaky structures.”
Low-frequency dynamics in a shock-induced separated flow (2016, background): “Based on DNS data of a Mach 2.9 compression-ramp STBLI, Priebe & Martín (2012) found evidence for low-frequency variations of the turbulence intensity in the shear layer.”
Unsteady effects of strong shock-wave/boundary-layer interaction at high Reynolds number (2017, methodology): “Only when using a similar instantaneous separation surrogate as that of Ganapathisubramani et al. (2009) were the authors able to detect significant correlations, demonstrating the uncertainty of such methods when applied to experimental measurements.”
Flow physics and RANS modelling of oblique shock/turbulent boundary layer interaction (2013, methodology): “While this relationship makes intuitive sense (that is, the separation location strictly lags the upstream velocity signal), it is in contrast to Ganapathisubramani et al. (2009), who observed the tails of their signal extend into the negative time delay regime up to 1t ≈ −30δ0/u∞.”
Low-Frequency Unsteadiness of Shock Wave/Turbulent Boundary Layer Interactions (2014, methodology): “For example, they investigated the mechanism proposed by Ganapathisubramani et al. (2007, 2009) that there exists a strong correlation between fluctuations in the upstream boundary layer and the separated flow motion.”
