In this work numerical calculations have been performed to simulate the heat transfer and fluid flow in a transonic high-pressure turbine stage. The calculations have been performed using both the shear-stress transport (SST) k-w model and the v2-f model in order to assess the capability of these models to predict the heat transfer and pressure distributions. The stator and rotor rows interact via a mixing plane, which allows the stage to be computed in a steady manner. The results of fully 3D CFD simulations are compared with experimental heat transfer and aerodynamic results available for the so-called MT1 turbine stage. The predicted heat transfer and static pressure distributions show reasonable agreement with experimental data.
