Compensating cooling on the suction surface of the blade by the jets of the film holes on the endwall

Case Studies in Thermal Engineering
The coolant ejected from the film holes on the gill region of the blade deflects to the blade tip in the action of the cascade passage vortices, resulting in the local film cooling failure on the suction surface near the endwall. This paper introduces an
