Management and Control of Unsteady and Turbulent Flows.

Abstract

Progress in four areas of research has been achieved during the first year. I. Controlled Transitioning Boundary Layers: phase coupled plane TS waves and oblique waves are used to study various types of transition including detuned modes. II. Turbulent Boundary Layer Structure and Control: the structures responsible for the turbulence production in high Reynolds number boundary layers have been documented and manipulated. III. Management of Unsteady and Three-dimensional Flows: flows over airfoils, axisymmetric forebodies, vortex-wing interactions, and wing-body junctions, are examined with and without passive and active flow manipulators including zero-mass base bleed. IV. Scanning Laser Anemometry: a technique capable of mapping the flowfield in a plane has been developed. Keywords: Unsteady flow, Separated flow, Flow control, Instrumentation. (aw)
