Abstract
In this paper, a stochastic term is introduced in the subgrid-scale model of the X-LES method in order to improve the computation of turbulent free shear layers. These shear layers may develop too slowly in X-LES and similar DES-type methods, even when fine grids and high-order numerical methods are used. For a plane free shear layer, the stochastic subgrid-scale model induces rapid development of fully 3D turbulence in contrast to the standard method for which the flow remains purely 2D. A comparison is made with experimental results and with results of a zonal RANS–LES method with LES content added at the RANS–LES interface.
