Abstract: Turbulent shear flows containing high levels of instantaneous turbulence or mean reversed flow, separation and reattachment, occur in many technical applications. The purpose of this paper is to describe the topology of a separated/reattached flow, to present a set of measurements of the separated flow behind a backward-facing step, and to perform an analysis of the data. The experiment has been conducted at a Re number of 84000, which was estimated based on the step height

Keywords: turbulent separated flow, shear layer, mixing layers, boundary layers
