Abstract: The characteristics of the wake of a rotating flat plate with a large attack angle were investigated experimentally with special attention of the flow near the tip of the plate. When the tip clearance is small, the dead air region becomes large towards the tip of the plate and the shear layer of the suction side of the plate curves outward as a result of the accumulation of low-energy fluid. On the other hand, when the tip clearance is large, the leakage flow is so large that the leakage vortex is generated from the trailing edge of the suction side and the shear layer forms by contacting the leakage flow and the dead air region. The variations of the flow rate and the momentum of the wake flow are closely related to those of the leakage flow.
