Drag reduction and subcritical turbulence in controlled pipe flows
Abstract Content of image described in text. Pipe flow controlled by streamwise-travelling waves of azimuthal wall velocity is studied using direct numerical simulations at a bulk Reynolds number italic Re Subscript b Baseline equals 4900 Reb=4900 $\textit{Re}_b=4900$ . A comprehensive analysis of drag reduction shows...
