Effect of combined hole configuration on film cooling with and without mist injection
Turbine blades operate under a harsh environmental condition, and the inlet temperature of gas turbines is increasing with requirement of high engine effi-ciency. Some cooling schemes are adopted to prevent these blades from the ther-mal erosion of the hot mainstream. Film cooling technology is used widely and effectively in gas turbines. The coolant air is suppressed to the wall by the main-strea
