Abstract
A brief summary of the recent progress achieved by the author’s research group on active turbulence control for drag reduction in turbulent boundary layers is presented. All control schemes are developed on the premise that the most effective way to control turbulent boundary layers is through proper manipulation of the near-wall streamwise vortices. Numerical experiments have been performed to test various control schemes, which involve applications of neural networks, suboptimal control theory, the Goore scheme and systems control theory. It is shown that each approach leads to a successful control scheme, thus proving the validity of the premise mentioned above.
