Research on transition in incompressible flow
Abstract
This study is concerned with the transition of an incompressible boundary layer, with zero pressure gradient and low free-stream turbulence. Mean velocity and turbulence profiles are presented. The development of the Tollmien-Schlichting waves is clearly shown until the turbulent spots appear. The intermittency phenomenon is studied by conditional sampling of the hot wire signal; laminar and turbulent properties of the flow during transition are separately determined by this technic.
