The turbulence statistics of an unsteady separated ยฏow was experimentally investigated. A backward-facing step ยฏow at Re 3700 was chosen as the test case, where periodic perturbation was introduced from its step edge. A two-dimensional particle imaging velocimeter (PIV) was used in the ยฏow-ยฎeld meas
