Abstract

This paper describes a method that allows the effect of film cooling on the capacity of a turbine to be computed. The model is based on fundamental cooling performance parameters and is applicable to situations in which a mainstream flow is displaced by a partially mixed film cooling layer. The purpose is to quantify the error that is incurred in the engine situation when common—but simplified—assumptions are made regarding the flow, and where necessary, to provide a means of correcting the capacity for the effect of the film cooling flow.
