Formulation of models to calculate the thermal boundary conditions in the channels of a turbine blade cooling system
Abstract
The task of formulating models to calculate the heat transfer coefficients and the temperature of the cooling air in the channels of a turbine blade cooling system is considered. Three models to calculate the heat transfer coefficients and three models to calculate the temperature of the cooling air are analyzed. The models are formulated so the heat transfer coefficients and the cooling air temperature are calculated using regression correlations; in witch the engine gas path measured parameters are used as arguments To analyze the model’s robustness, 10 defects reflecting the change in the technical conditions of the engine gas path and its working conditions were considered. The best model to calculate the heat transfer coefficients and the temperature of the cooling air is selected based on the analysis of the obtained results.
