The behavior of a separating shear layer and its reattachment is clarified experimentally when free stream turbulence is provided for six separate cases in a backward-facing step flow. The reattachment point was determined by a thermal tuft probe. A hot-wire anemometer was used for measurements of mean velocity and turbulence. Reynolds number based on step height was 3.2×104, turbulence level ranging from 0.25 to 7.4%. The turbulence level upstream of the step is the higher, the shorter reattachment length is obtained, while no effect of step geometry on reattachment is observed.
