An efficient method of synthetic turbulence generation at LES inflow in zonal RANS–LES approaches to computation of turbulent flows

A new simple and efficient algorithm is proposed for generating turbulent content at the RANSLES interface in the framework of hybrid RANS–LES approaches to computation of turbulent flows. Advantages of this algorithm over existing analogs are demonstrated both for the canonical wall bounded and free shear turbulent flows and for a complex flow past a wall-mounted hump which includes boundary layer separation induced by adverse pressure gradient, reverse flow region, and relaxation of the boundary layer downstream of its reattachment.
