Abstract

Boundary-layer separation at a backward-facing step of a flat plate has been investigated in a low-turbulence wind tunnel with Particle Image Velocimetry (PIV). The experiments focused on the flow pattern behind the step at the Reynolds number based on its height of about 1000. Under quiet environmental and low-Re-number conditions, laminar flow separation was observed behind the step subjected to a small amount of the shear-layer instability. Examination of natural and controlled velocity perturbations in the separation region indicated that the version of PIV used in the present study is an appropriate tool to deal with linear-instability details that is normally done through hotwire measurements.
