Componentwise energy amplification in channel flows (2005, methodology): “We show this using the relative scaling of the different input–output system components with the Reynolds number.”
Colour of turbulence (2016, background): “…flow control Despite initial successes of model-based feedback (Joshi et al. 1997; Cortelezzi & Speyer 1998; Bewley & Liu 1998; Lee et al. 2001; Högberg et al. 2003a,b; Kim & Bewley 2007) and sensor-free (Fransson et al. 2006; Jovanović 2008; Moarref & Jovanović 2010; Lieu et al. 2010;…”
Machine Learning Control – Taming Nonlinear Dynamics and Turbulence (2016, background): “For example, in fluid dynamics there are numerous success stories of linear model-based flow control, including transition delay in a spatially developing boundary layer on a flat plate and in channel flow [29, 136, 135, 63, 142, 13, 11, 12, 244, 245, 101], reducing skinfriction drag in wall turbule”
Input–output analysis, model reduction and control of the flat-plate boundary layer (2009, background): “For instance in our case, # xj consist of the Chebyshev integral weight functions ( Hanifi, Schmid & Henningson 1996 ) in the wall normal direction and a trapezoidal rule in the streamwise direction.”
State estimation in wall-bounded flow systems. Part 2. Turbulent flows (2006, unknown): “Estimator gains and the corresponding physical-space kernels In Högberg et al. (2003a), the covariance Q was modelled with a spatially uncorrelated stochastic forcing, Q = I .”
Issues in active flow control: theory, control, simulation, and experiment (2004, background): “While there has been success in using linear control for wall bounded turbulence ranging from simple opposition control [83,87,107] to modern control theories [103,106], it seems likely that this success is due, in part, to the importance of linear processes in the near-wall region [94,95].”
