Film cooling has an inherent complex flow structure due to the injection of coolant into the mainstream boundary layer. Phenomena such as film blow-off at high blowing rates are part of the experience when using discrete holes to inject the coolant. Inside a turbine, this flow structure is further complicated by the introduction of free stream turbulence. Knowledge of the effect free stream turbulence has on film cooling effectiveness serves to improve the prediction of coolant requirements during turbine operation . | Effect Of High Free Stream Turbulence On Film Cooling Using Double Row Of 30-slant-hole Injectors by Lilith I Sorensen, Paperback | Indigo Chapters
