Reynolds-number dependence of turbulent skin-friction drag reduction induced by spanwise forcing
This paper examines how increasing the value of the Reynolds number $Re$ affects the ability of spanwise-forcing techniques to yield turbulent skin-friction drag reduction. The considered forcing is based on the streamwise-travelling waves of spanwise-wall velocity (Quadrio et al. , J. Fluid Mech. , vol. 627, 2009, pp. 161–178). The …
