...Jia-Jun Hu; Bai-Tao An This paper investigates the influence of ribbed crossflow on the film cooling performance of a turbine rotor blade. A pressure-sensitive paint measurement technique was employed to measure the effectiveness of film cooling. The discharge coefficients were also measured...

... edge is hardly covered by the cooling film. Upon entering the passage, the passage crossflow propels the coolant flow from the pressure side to the suction side, and the cooling air around the passage vortex liftoff line is drawn into the mainstream. Because of these two reasons, the endwall close...
