A simple model for low-frequency unsteadiness in shock-induced separation (2009, background): “This behaviour is very similar to results from a DNS of a Mach 2.9 compression ramp by Wu & Martin (2008), with shock motions correlated with low-frequency bubble unsteadiness.”
Characterization of coherent vortical structures in a supersonic turbulent boundary layer (2008, methodology): “The computational strategy to solve the governing equations relies on a finitedifference approach that has been extensively validated in previous works both for isotropic decaying compressible turbulence and for wall-bounded turbulent supersonic flows (Pirozzoli & Grasso 2004, 2006).”
Large-eddy simulation of low-frequency unsteadiness in a turbulent shock-induced separation bubble (2009, methodology): “Similarly, the DNS of Pirozzoli and Grasso [37] covered only 25δ0/U∞, despite the use of a Reynolds number about a third that of the experiment.”
Analysis of unsteady behaviour in shockwave turbulent boundary layer interaction (2012, background): “Direct numerical simulations (DNSs) (Adams 2000; Pirozzoli & Grasso 2006; Wu & Martin 2007) and large eddy simulations (LESs) (Loginov, Adams & Zheltovodov 2006; Touber & Sandham 2009) of the † Email address for correspondence: muzio.grilli@aer.mw.tum.de shock/boundary-layer interaction started to…”
Confinement effects in shock wave/turbulent boundary layer interactions through wall-modelled large-eddy simulations (2014, background): “Pirozzoli & Grasso (2006) proposed an acoustic resonance mechanism to be responsible for sustaining the low-frequency, oscillatory motion of the separation point, and also developed a simplified model.”
Three-dimensional instantaneous structure of a shock wave/turbulent boundary layer interaction (2009, methodology): “In particular, Pirozzoli & Grasso (2006) carried out a DNS on an incident SWTBLI at Mach 2.25 and proposed that the large-scale unsteadiness was associated with an acoustic feedback mechanism, similar to what is involved in the generation of tones in cavities and screeching jets.”
Effects of upstream boundary layer on the unsteadiness of shock-induced separation (2006, background): “Pirozzoli & Grasso (2006) performed numerical studies (DNS) of a reflected shock wave/boundary layer interaction and proposed that the large-scale low-frequency unsteadiness is due to a resonance mechanism that establishes in the interaction region.”
Low-order stochastic modelling of low-frequency motions in reflected shock-wave/boundary-layer interactions (2011, methodology): “…forcing could be any significantly long upstream coherent structures (see Ganapathisubramani et al. 2007, 2009, and references therein) or particular flow features within the interaction itself (see Pirozzoli & Grasso 2006; Dussauge & Piponniau 2008; Piponniau et al. 2009, and references therein).”
Flow physics and RANS modelling of oblique shock/turbulent boundary layer interaction (2013, methodology): “(3.12e) The frequencies given in (3.12) are approximately 80 % greater than the frequencies predicted by Pirozzoli & Grasso (2006) for a similar interaction, a fact which reflects the practical difficulties of obtaining accurate values for Uc and c−.”
Low-Frequency Unsteadiness of Shock Wave/Turbulent Boundary Layer Interactions (2014, methodology): “…fluctuations are highly coherent with the fluctuations in the intermittent region indicated a downstream source for the unsteadiness. www.annualreviews.org • Shock/Boundary Layer Interaction Unsteadiness 479 Pirozzoli & Grasso (2006) used DNS to simulate a Mach 2.25 impinging shock interaction.”
Numerical Methods for High-Speed Flows (2011, methodology): “Pirozzoli & Grasso (2006) performed a DNS study with flow conditions similar to Garnier et al. (2002), using a seventh-order WENO scheme.”
Unsteady effects of strong shock-wave/boundary-layer interaction at high Reynolds number (2017, background): “Further, the authors detected upstream-travelling acoustic waves within the separation bubble, confirming the possibility of the acoustic feedback mechanism proposed by Pirozzoli & Grasso (2006).”
A scaling analysis for turbulent shock-wave/boundary-layer interactions (2013, background): “…& Dolling 2007a; Wu & Martin 2008; Ringuette, Wu & Martin 2008) and incident-reflecting shock interactions (Green 1970; Dupont, Haddad & Debiève 2006; Pirozzoli & Grasso 2006; Touber & Sandham 2008; Piponniau et al. 2009; Humble et al. 2009a; Souverein et al. 2009; Polivanov, Sidorenko & Maslov…”
Analysis of shock motion in shockwave and turbulent boundary layer interaction using direct numerical simulation data (2007, background): “Pirozzoli & Grasso (2006) analysed direct numerical simulation (DNS) data of a reflected shock interaction and proposed that a resonance mechanism might be responsible for the shock unsteadiness.”

Direct numerical simulation of transonic shock/boundary layer interaction under conditions of incipient separation (2010, methodology): “…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).”
