Abstract: A modified version of the Baldwin-Barth k-ℜ two-equation turbulence model is proposed, in which the near-wall function fμ is based on the ratio of the large eddy and the Kolmogorov time scales. This results in a model applicable to both wall-bounded and free shear flows which, nevertheless, does not require explicit knowledge of local distance to walls, rendering it useful within both structured and unstructured computational frameworks for flow predictions involving complex geometries. The new model’s predictive capability is demonstrated through a number of flow cases.
