Turbulent Boundary Layer Structure, Drag Reduction.

Abstract

The research work has progressed along the following lines: 1) continuation of theoretical work on the effects of large-eddy breakup devices on turbulent eddies; 2) theoretical study of the role of pressures in the wall turbulence generation process; 3) application of a theoretical model for designing 'smart' wall boundary layer control; 4) use of a new bursting model for predicting the mean velocity profile near a wall; 5) development and application of a new skin friction probe, and 6) initial design of a 'smart' wall producing a controlled travelling disturbance. Keywords: Skin Friction Probe; Turbulent Flow; LEBU(Large Eddy Breakup); Boundary Layer Control.
