Assessment of transition modeling and detached-eddy-simulation of a wind-turbine airfoil near stall
Accurate prediction of transition, separation, and wake unsteadiness remains challenging for wind-turbine airfoils. This study investigates the DU 91-W2-250 wind-turbine airfoil at Re c = 3 × 10 6 using fully turbulent and transitional shear-stress transport (SST) k – ω unsteady Reynolds-averaged Navier...
