• Initial response of a turbulent channel flow to spanwise oscillation of the walls (2003, methodology): “As happened for the fully developed oscillating Stokes layer described by Quadrio and Sibilla [3] and by Choi et al [25] for turbulent pipe flows and by Choi and Clayton in [23] for a flat-plate boundary layer, the three-dimensional turbulent flow field does not alter the superimposed transverse flo”
• Streamwise-travelling waves of spanwise wall velocity for turbulent drag reduction (2009, background): “In the oscillating-wall case, the space-averaged velocity profile follows closely the laminar solution, which has led to a scaling parameter for drag reduction (Choi et al. 2002; Quadrio & Ricco 2004). Analogously, Viotti et al. (2008) have found that the laminar layer induced by the standing waves ”
• Near-wall streak modification by spanwise oscillatory wall motion and drag-reduction mechanisms (2012, methodology): “…arising for actuation periods T+ below 150, collapse on a line in a plot that relates the drag-reduction level to a parameter S+, first proposed by Choi et al. (2002) and combining T+, the wall-scaled amplitude of the wall velocity, the penetration depth of the Stokes layer and the maximum…”
• Critical assessment of turbulent drag reduction through spanwise wall oscillations (2004, methodology): “+2 .T his corresponds to T + opt,W =2 5π ≈ 78.5 with the choice of parameters by J.-I. Choi et al. (2002) , i.e.”
• Reynolds-number dependence of turbulent skin-friction drag reduction induced by spanwise forcing (2015, methodology): “(4.1) The power-law assumption was originally adopted by Choi et al. (2002) to fit early DNS-computed drag-reduction results obtained for the spanwise-oscillating wall, and it is not endowed with a specific physical significance.”
