Flow physics and RANS modelling of oblique shock/turbulent boundary layer interaction (2013, methodology): “Touber & Sandham (2009b) and Hadjadj et al.

Direct numerical simulation of transonic shock/boundary layer interaction under conditions of incipient separation (2010, background): “…amplification of Reynolds stresses in the APG region, especially in the mixing layer, where the shedding of vortical structures occurs, as also found by Délery (1983), and for supersonic interactions by Adams (2000), Pirozzoli & Grasso (2006), Wu & Martin (2007) and Touber & Sandham (2009).”
Confinement effects in shock wave/turbulent boundary layer interactions through wall-modelled large-eddy simulations (2014, methodology): “Furthermore, when spanwise periodicity is used in simulations, Touber & Sandham (2009b) found that the size of the separation bubble varies with the width of the domain: if the computational domain is not sufficiently wide in the spanwise direction, the separation bubble size is over-predicted.”
Low-order stochastic modelling of low-frequency motions in reflected shock-wave/boundary-layer interactions (2011, methodology): “This does not mean that specific forcing from upstream (see Ganapathisubramani et al. 2007, amongst others) or downstream (see Pirozzoli & Grasso 2006; Robinet 2007; Piponniau et al. 2009; Touber & Sandham 2009b) does not play a role, but that they are not necessary.”
Low-Frequency Unsteadiness of Shock Wave/Turbulent Boundary Layer Interactions (2014, methodology): “Touber & Sandham (2009) performed large-eddy simulations of the impinging SBLI configuration with an 8◦ shock generator to simulate the experiments by Dupont et al. (2005).”
A scaling analysis for turbulent shock-wave/boundary-layer interactions (2013, background): “…are still under debate, it has been shown recently that in separated cases, the low-frequency unsteadiness of the separation shock is also fairly independent of the particular geometry of the flow (Dussauge, Dupont & Debiève 2006; Dupont et al. 2006; Wu & Martin 2008; Touber & Sandham 2009b).”
