Abstract

The experimental research results of the features of formation and development of the coherent vortical structures in the half-cylindrical trench and also statistical characteristics of velocity field are submitted. The scales and location of the coherent vortical structures inside of the trench are determined. The influence of the vortex motion in the cavity on a boundary layer above a flat surface with the local half-cylindrical trench is shown.
