We review some fundamentals of turbulent drag reduction and the turbulent drag reduction
techniques using streamwise traveling waves of blowing/suction from the wall and wall …

A simple expression is derived of the componential contributions that different dynamical
effects make to the frictional drag in turbulent channel, pipe and plane boundary layer flows. …

The Reynolds-number dependence of the drag reduction achievable by diminishing to zero
the near-wall turbulent velocity fluctuations is clarified. This reduction could be obtained by a …

… In this section, we overview the recent work made by Fukagata et al. (2005). First, an explicit
mathematical relationship is derived of laminar and turbulent contributions to the wall heat …

… which corresponds to the di— rect effect of opposition control (Fukagata and Kasagi. 2003);
and the long time scale in the region near the wall. which re— flects the effect of forcing in …

… and friction drag (Fukagata, Iwamoto & Kasagi 2002) and the theoretical limit of active
friction drag reduction control for flows in a plane channel (Bewley 2009) and in arbitrary ducts (…

In order to investigate the possibility of smart drag reduction in high Reynolds number wall
turbulence, direct numerical simulation of a turbulent channel flow at Reτ= 1160 was made. …
