Book Description
This linear model was used to develop reduced-order linear-quadratic-Gaussian (LQG) controllers. While these controls could achieve significant drag reduction, they appeared to be a performance limit. However, they could induce transient sublaminar drag under certain conditions. A nonlinear minimization using full-order nonlinear simulations was attempted to capture this transient behavior on a periodic basis. The upstream traveling wave was discovered in the course of that study.

Book Description
Since man has been trying to fly, a war against drag been engaged. At the present time, drag reduction is an industrial challenge in Aeronautics which justifies the efforts devoted to this topic. One facet of these efforts deals with the skin-friction drag reduction. Two directions are followed. The first one is the manipulation of turbulent boundary layers. By altering the formation of turbulence or by modifying its characteristics it is hoped to decrease the turbulent skin-friction. The second direction concerns the action on laminar-turbulent transition. By delaying the occurrence of the turbulent regime enormous skin friction reductions are possible. This Lecture Series on Skin-Friction Drag Reduction is aimed at giving an overview of the state of the art on the various means which are being studied to obtain significant gains.
