Predictions and Measurements of Film-Cooling on the Endwall of a First Stage Vane
In gas turbine development, the direction has been toward higher turbine inlet temperatures to increase the work output and thermal efficiency. This extreme environment can significantly impact component life. One means of preventing component burnout in the turbine is to effectively use …

A Full Coverage Film Cooling Study: The Effect of an Alternating Compound Angle
… of this work is the quantification of local heat transfer augmentation and adiabatic film cooling effectiveness for two full-coverage film cooling geometries. Experimental data was acquired with a scientific grade CCD camera, where images are taken over the heat transfer surface, which is …
