Large-scale amplitude modulation of the small-scale structures in turbulent boundary layers (2009, background): “Such autonomous views are based largely on insightful low-Reynolds-number simulations by Jim´enez & Pinelli (1999) and Schoppa & Hussain (2002).”
Colour of turbulence (2016, background): “Schoppa & Hussain (2002); Hœpffner, Brandt & Henningson (2005a) further identified a secondary growth (of the streaks) which may produce much larger transient responses than a secondary instability.”
Linear energy amplification in turbulent channels (2006, background): “There are numerous works on the stability of the sublayer streaks (see for instance Schoppa & Hussain 2002) showing that they must have a finite amplitude before they become unstable.”
The engine behind (wall) turbulence: perspectives on scale interactions (2017, background): “Common features of the solutions are wavy low-speed streaks flanked by staggered quasi-streamwise vortices, a picture consistent with observations in full turbulence by, e.g., Schoppa & Hussain (2002).”
Direct numerical simulation of turbulence in a sheared air–water flow with a deformable interface (2003, background): “The lack of consensus is even more acute as to which of the streamwise velocity streaks or quasi-streamwise vortices are directly implicated in the turbulence self-sustaining mechanisms (Jimenez & Pinelli 1999; Schoppa & Hussain 2002).”
The Significance of Simple Invariant Solutions in Turbulent Flows (2011, background): “…of mean shear flow by streamwise vortices (Kline et al. 1967), and it is believed that the streamwise vortices arise from the instability of the streak and the subsequent nonlinear vortex stretching in the streamwise direction (Hamilton et al. 1995, Kawahara et al. 2003, Schoppa & Hussain 2002).”
MECHANISMS ON TRANSVERSE MOTIONS IN TURBULENT WALL FLOWS (2003, methodology): “Specifically, the normal vorticity, whose amplitude plays an important role in the streak instability process according to the theory by Schoppa & Hussain (2002), is lowered substantially.”
Using digital holographic microscopy for simultaneous measurements of 3D near wall velocity and wall shear stress in a turbulent boundary layer (2008, background): “There is a consensus that streamwise or quasi-streamwise vortices dominate in the inner layer of the turbulent boundary layer, and are involved in the socalled ‘‘bursting’’ processes (Brooke and Hanratty 1993; Hamilton et al. 1995; Jimenez 2005; Jimenez et al. 2001; Kim et al. 1987; Robinson 1991; ”
Linear non-normal energy amplification of harmonic and stochastic forcing in the turbulent channel flow (2010, background): “…mechanism is now understood to be based on the strong amplification of the streaks from quasi-streamwise vortices followed by the breakdown of the streaks leading to the ‘refuelling’ of the quasi-streamwise vortices (Hamilton, Kim & Waleffe 1995; Waleffe 1995; Schoppa & Hussain 2002).”
Cascades in Wall-Bounded Turbulence (2012, background): “…and Hoyas & Jiménez (2006), or the boundary layers by Lee & Sung (2007, 2011), Schlatter et al. (2009), Simens et al. (2009), Wu & Moin (2010), and Sillero et al. (2010), with δ+ ≈ 1,000–2,000, are comparable to most well-resolved experiments and have approximately a decade of scale disparity.”
