Abstract

This paper presents results of numerical simulations of flat plate film cooling carried out with the use of commercial code ANSYS CFX in comparison with experimental data. In this study single row of cylindrical holes configuration with relative pitch t/d = 3 and at blowing ratios m = 0.5; 1.0; and 1.4 was reviewed. It was shown that standard SST turbulence model (with constant values by default) cannot provide film cooling effectiveness simulation results agreement with experimental data with allowable accuracy at m > 0.5. Adaptation of SST turbulence model by means of a1 constant and turbulent Prandtl number correction enabled to improve accuracy of film cooling numerical simulations. The effect of the adaptation model on the heat transfer and pressure drop calculation results was considered as well.
