Taming Near-Wall Streamwise Vortices: A Modus Operandi for Boundary Layer Control. The resulting feedback laws are applied to a low Reynolds-number turbulent channel flow. Numerical experiments indicate that both approaches yield substantial drag reduction. The application of a system theory approach to the feedback stabilization to delay the transition in a laminar channel flow is also discussed.

Dynamics of the Structures of Near Wall Turbulence of velocity streaks from the advection of the mean profile by streamwise vortices, and the generation of the vortices from the instability of the streaks. Interrupting any of those processes leads to laminarisation of the wall. The production of secondary vorticity at the wall is not important in turbulence generation.

On the Space-Time Structure of Axisymmetric Rotating Flowseating motion. This is accompanied by the continued formation of axisymmetric spikes on the edge of the breakdown bubble which travel along the central vortex core toward the rotating end-wall. The data analysis is performed by using the proper orthogonal decomposition.
