Turbulent Boundary Layer Structure and Drag Reduction

Abstract

During the grant period the research work has progressed along the following lines: 1) Development of a localized three-dimensional disturbance in a shear flow; 2) Exploration of new instability modes for inviscid and viscous shear flows; 3) Analysis of polymer drag reduction mechanisms; and 4) Experiment to study spanwise growth of transition spots in a plane Poiseuille flow.
