Dynamic Effects of Suction/Heating on Turbulent Boundary Layers.

Abstract

The goals of this research were to constructively interact with and alter vortical structures embedded within boundary layers. The concept of selective interaction was developed which utilized information about the location of the vortical structures so that the interaction could be tailored to more efficiently alter the eddies. Different types of mechanisms were deployed to alter the eddies including suction, blowing, actuators, etc. These methods altered the development of streamwise vortices sufficiently that their breakdown and mixing were significantly delayed.
