Flow passing a heated square cylinder is investigated using a hybrid LES-RANS approach on unstructured grids at a moderate Reynolds number of 22,050. The implicit sub-grid scale model is apply to LES, and two turbulence models, the Spalart-Allmaras model and the SST k-ω model, are employed for near-wall RANS. Combined with LES, both models present good predictions of the time- and phase-averaged velocity...
