| Abstract: | Experiments are performed on a flat plate with a transverse suction slit in the Reynolds number range 5 × 105 < Re < 1.1 × 106. Mean velocity profiles, RMS values are measured with hot wire anemometry. Friction velocity is numerically calculated. The experiments showed that a classical boundary layer parameter α is related to the suction coefficient Sc with an equation of the form: .The value of A seems to depend strongly on the relative location with respect to suction slit and possibly weakly on Reynolds number. |
