• Transition in boundary layers subject to free-stream turbulence (2004, methodology): “The streaks soon reach an amplitude of the order of 30% of the free-stream velocity, a sufficiently high value for the onset of a secondary instability (Andersson et al. 2001).”
• The lift-up effect : The linear mechanism behind transition and turbulence in shear flows (2014, background): “This is indeed what happens in the case of secondary streak instability, where an inflectional type of instability develops on the regions of largest vorticity induced by streamwise elongated perturbations (Reddy et al., 1998; Andersson et al., 2001; Brandt et al., 2003).”
• Global three-dimensional optimal disturbances in the Blasius boundary-layer flow using time-steppers (2010, background): “As shown by Andersson et al. (2001), among others, in the range of validity of the boundary layer equations, there is a coupling between the streamwise and spanwise length scales of the disturbance.”
• Breakdown mechanisms and heat transfer overshoot in hypersonic zero pressure gradient boundary layers (2013, background): “Andersson et al. (2001) studied secondary instability due to optimal streaks in incompressible boundary layer flow.”
• Amplification of coherent streaks in the turbulent Couette flow: an input–output analysis at low Reynolds number (2010, background): “Streaks of large enough amplitude undergo inflectional instabilities (Waleffe 1995; Reddy et al. 1998; Andersson et al. 2001) playing a crucial role in subcritical transition to turbulence.”
• Transition of streamwise streaks in zero-pressure-gradient boundary layers (2002, methodology): “Andersson et al. (2001) have shown that the streamwise velocity of the secondary instability modes is concentrated around the critical layer, i.e. the layer of constant value of the mean field velocity corresponding to the phase speed of the disturbance which is u = 0.81U∞ in the present case, thus…”
• Statistical structure of self-sustaining attached eddies in turbulent channel flow (2015, background): “…streak instability also appears to give the ‘speed’ of the streaky motions: the most unstable wave contains non-zero phase speed, which is often given by the critical layer of the corresponding ‘two-dimensional streaky’ base flow (Andersson et al. 2001; Schoppa & Hussain 2002; Park et al. 2011).”
