Abstract
AbstractA new zonal multi‐domain Reynolds averaged numerical simulation/large‐Eddy simulation (RANS/LES) method is presented and assessed. The main occurring problem is the coupling at the domain interfaces between a 1D or 2D, ensemble averaged solution computed with the RANS approach with the 3D, filtered, unsteady solution obtained using the LES approach. Both low‐ and high‐normal velocity interface cases are considered, resulting in a fully general approach. A coupling procedure well suited for cell‐centred finite volume numerical method is proposed. Numerical tests are carried out for the plane channel and the plane plate with a blunt trailing‐edge configurations. Copyright © 2002 John Wiley & Sons, Ltd.
