Abstract
A numerical investigation of a fully three-dimensional swept wing geometry featuring separation from a curved leading edge is presented. The Implicit Large-Eddy Simulation strategy based on a third-order high-resolution method for discretising the advective fluxes and a third-order Runge-Kutta time-stepping scheme with extended stability region has been employed. No attempt to incorporate a wall-model has been made. Instead, the boundary layer is fully resolved over the majority of the wing. Qualitative and quantitative comparisons with experimental oil-film visualisations and three-dimensional LDA measurements show very good agreement between the experiment and the numerically predicted flow structures, as well as velocity and stress profiles near the wing. Furthermore, data from a hybrid RANS/LES simulation has been included for comparison.
