Turbulent Boundary Layer Structure and Drag Reduction.

摘要

Work progressed along the following lines: i) completion of the development of kinematic wave theory for propagation of waves for wave trains or wave packets with small dissipation through homogeneous or non-homogeneous media; ii) development of a simplified model for the influence of a large eddy breakup device on turbulent boundary layer eddies; iii) completion of experimental and theoretical studies of transition spots in a plane channel flow; iv) preparation of experimental research on flat-plate laminar and turbulent boundary layers.
