| Abstract | ||||
| An experimental investigation was performed to examine the effect of film cooling from different shape holes at the leading edge of a flat plate. The interaction of a heated jet with a deflecting flow has been performed. The secondary flow is introduced at different angles to the mainstream flow direction with single row of holes. Visualization studies using yarn tufts are reported. The influences of hole geometry; mainstream boundary layer thickness are described significant improvements in the film cooling effectiveness are observed by having the coolant and passages widened before the exit of the secondary fluid. "Normal-inclined" injection gives superior results. | ||||
