Abstract
Turbulence is controlled in boundary layer or wall-bounded fluid flow fields having a turbulent wall region which under natural conditions, has an average system of roll pairs or streaks adjacent the surface, and extending in the direction of flow, by locally introducing into the turbulent wall region, by passive means, a disturbance that enhances or inhibits the roll pairs thereby locally increasing or decreasing the turbulence in the flow field.
