Abstract�� Wall pressure distribution induced by the saw-tooth flap has been investigated with electronic pressure scanner in wind tunnel. The results showed that the shear layer of the saw-tooth flap separated at x/h=(6 upstream and reattached at x/h≈20 downstream, which is the same with the plate flap; The transverse location of the flap has little influence on the mean pressure distribution, and the distribution of pressure fluctuation along the saw-tooth groove is greater than that along the saw-tooth tip; The saw-tooth can block the flow and much more effectively reduce the pressure fluctuation downstream.
Keywords�� flow separation   saw-teeth   pressure distribution   flow reattachment   flap
