| Abstract: | An experimental study was undertaken to locate the transitional separation bubble which often occurs on airfoil operating at low Reynolds numbers. The surface.hot film gages on the surf ace of airfoil gave the oscillograms of a voltage and the RMS value of a fluctuating voltage. The points of laminar boundary layer separation and turbulent boundary layer reattachment were obtained from these results. Then the transitional separation bubble was located. |
