In this study, a blended IDDES model and a correlation-based transitional model were newly coupled in OpenFOAM for simulating flow involving massive flow separation and the layer transition. Validations have been taken on the massively separated flow around NACA0021 airfoil at AoAs from 20 to 90. The force coefficients predicted by simulations have a good comparison with the experimental data.
