MANAGEMENT AND CONTROL OF TURBULENT SHEAR FLOWS

This survey will begin with a few historical aspects, describe some pa ssive and active management methods, and discuss selected examples of manipulation of leading edge separation. It will then deal with some t ypical flow phenomena which are important for the manipulation of turb ulent shear flows. A display of active means to manipulate open separa tion will be followed by a practical example of forcing a separated bo undary layer to reattach and to form a closed reverse-flow region. The survey will end with a few remarks on control.
