Comparison of Correlations and Experiments for Prediction of Vane Film Cooling in Gas Turbines

• In an earlier report by Bradley, a number of correlations from the open literature were presented and evaluated. All these correlations manage to accurately describe the film cooling eectiveness for the experiments they are based on, but there is doubts regarding the general predictive value of these correlations, especially for engine-like conditions. The correlations have now been analysed to investigate their predictive capabilities - especially the general applicability of correlations is in focus, for example for geometries or flow conditions slightly dierent than those for which the correlations were originally designed.
