TURBULENCE MEASUREMENTS IN THE BOUNDARY LAYER OVER A STREAMWISE EDGE (CHINE)

Abstract

The turbulent boundary layer developing over a chine aligned with the flow provides a sufficiently complex three dimensional flow that include many of the mechanisms seen in turbulent flows encountered in practice. In this paper we present mean flow measurements and some turbulence measurements characterizing the evolution of the boundary layer in this simple geometry. The measurements indicate the presence of stress induced secondary flows as expected from studies in related geometries. The mean flow is seen to be asymmetric with respect to the corner bisector. This asymmetry is also seen to influence the turbulence field.
