The two-equation level of turbulent heat flux modelling is considered for application in film cooling instead of the turbulent Prandtl number concept. The investigations involve numerical analysis of mean and fluctuating temperature fields near the coolant injection inlet. The results of the implemented coupled v2- f-k0-E0 model are compared with measurement data for a flat plate cooled with compound angle orientation of discrete in-jection holes. The results of numerical analysis agree very well with the experimental data. The coupled model offers a detailed picture of gas turbine cooling problems without using time-consuming, inherently unsteady models.
