Research output: Contribution to journalArticlepeer-review


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 discretizing the advective fluxes and a second-order Runge-Kutta time-stepping scheme with an extended stability region have 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 oilfilm visualizations and three-dimensional laser Doppler anemometry 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 Reynolds-averaged Navier-Stokes and large-eddy simulation have been included for comparison.
