摘要: This study gives an insight into the corner flow around a wing mounted on flat plate. Reynolds-averaged Navier–Stokes simulations and experimental data are compared for Reynolds number based chord (Rec) equal to 3×105 angle of attack 12 deg. The plate boundary layers fully turbulent, momentum thickness incoming layer is Reθ=2200. It shown that simulation using Spalart–Allmaras model with Boussinesq closure predicts massive separation, whereas side, separation confined small area. Better predictions obtained when resorting quadratic constitutive relation closure. A comprehensive investigation numerical results performed get better understanding behavior t...
