The turbulent separated and reattaching flow formed over a backward facing step has been measured to investigate the unsteady phenomenon of the flow. Upstream of the reattachment point, the power spectrum analysis of the velocity fluctuation indicated the dominant frequency is shifting towards lower frequency, which is thought to be caused by the vortex pairing inside the shear layer. The velocity fluctuation with higher frequency and with larger amplitude is periodically observed at the shear layer edge near the reattachment point. When this fluctuation is observed, the smoke wire visualization picture showed that there is a kind of large smoke cluster downstream of the reattachment point.
