Abstract
A new subgrid-scale model giving nearly zero eddy-viscosity during the laminar and the transition stages of a flow is proposed on the basis of the structure-function model (Metais & Lesieur 1992). With this new model, a large-eddy simulation (LES) of the complete transition of a quasi-incompressible boundary layer is presented. At a computational c ost of about 80 CPU hours of Cray 2, statistics and visualizations ind icate that the essential features of the transition process and of the turbulent motion are correctly captured.
