A new technique of tandem hot-wire probe has been developed to measure the two-dimensional unsteady sepalated flows including backflow region around rectangular prisms at Reynolds numbers ranging from 104 to 105. Measurements of time-averaged and unsteady velocity distributions are made for stationary and oscillating models. The time-averaged and unsteady streamlines around these models are presented and their correspondance to aerodynamic forces are also discussed.
