In the particular approach herein proposed, RANS and LES are combined in order to achieve a detailed description of turbulent flows without incurring in infeasible computational effort. This model is based on the hybrid filter approach proposed by Germano [5]. One of the most interesting point of this approach, is that the equations obtained by filtering Navier–Stokes equations, already include terms which are able to represent the interactions between RANS and LES regions. Therefore no further artificial terms are needed to allow the appropriate energy and momentum transfer between RANS and LES. This approach has already been tested [8, 10] showing promising results.
