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 LEBULarge Eddy Breakup Boundary Layer Control.
