... investigated. The diffusion slot hole was first applied to the blade endwall. As a comparison, the cooling performance of the fan-shaped hole was also measured. Totally, six discrete-hole cooling configurations (two hole shapes × three layouts) were investigated. Experiments were performed in a seven-blade...
