Abstract
The zonal RANS–LES approach based on the algebraic EARSM Reynolds stress model is considered. Using the EARSM model makes it possible to increase the accuracy of modeling the turbulent parameters at the RANS–LES interface in the case of flows in asymmetric designs and near dihedrals. This favors the more accurate modeling of vortex structures by the synthetic turbulence generator and, as a consequence, the narrowing of the transition zone behind the RANS–LES interface. The application of this approach is analyzed with reference to the examples of flows in a square channel and an asymmetric diffuser.
