Distinctive features of vortical structures generation in separated channel flow behind a rib under transition to turbulence

Thermophysics and Aeromechanics Aims and scope

Abstract

Results of laboratory research and numerical simulation of 3D separated channel flow behind a semi-cylindrical spanwise rib in laminar and transitional to turbulence flow regimes are presented. Data on dynamics of flow structure and evolution of large-scale vortical structures generated in the obstacle wake zone have been obtained.
