Outline of Final Research Achievements

Ring-type plasma actuators utilizing dielectric barrier discharge were developed in order to carry out active control of the tip leakage flow in turbine rotors. The strength of two-dimensional leakage flow was changed by adjusting the tip clearance of a flat plate inserted into the wind tunnel test section. As a result of PIV analysis for evaluating effects of tip shapes of the flat plate, it was found that the effect for mitigating the leak flow is improved when the shape of the entrance and exit edge of tip surface is symmetrical. Active control of the tip leakage flow of linear and annular turbine cascades were also conducted by ring-type plasma actuators made of silicone print-circuit board. The tip leakage flow and the tip and hub passage vortices were reduced under lower Reynolds number.
