Abstract: A three-dimensional feature-based jet model is proposed for the numerical simulation of film cooling flows. The modelling is made in the near hole region and model coefficients are experimentally anchored. The model previously validated for streamwise jet injection cases is modified so that compound jet injection can be simulated. The modifications of the model concern the lateral trajectory of the jet and the structural change of the coolant Counter-rotating Vortex Pair (CVP). It is shown that the modelling strategy is relevant and robust for moderate compound angle injection and that higher injection angle necessitates deeper structural change of the modelling approach.
