Abstract [en]

Reliable correlations for predicting film cooling performance is one of the major considerations in the cooling analysis of today's gas turbine engines. In this study correlations have been derived for cylindrical holes positioned at three different positions on both the suction and pressure sides of a vane configuration at engine like settings. The blowing ratio ranges between 0.3-2.2 for the suction side and 0.9-6.55 for the pressure side. The density ratio is one. The correlation model derived here is inspired from Bunker with modifications in definition of the variables and adding extra terms. The extra terms obtained from the main variables are introduced into a stepwise regression method (statistical analysis) to find predictors with the highest contribution percentage. These variables are then utilized in the correlation for increasing model predictability. The proposed correlation is compared with existing correlations in terms of adjusted coefficient of determination R2 adj , where significant improvement is obtained. The applicability of the model to shaped holes is also discussed. Copyright © 2012 American Institute of Aeronautics and Astronautics, Inc.
