| Abstract: | In this paper, the effect of roughness sensitivity on the performance of the thick wind turbine airfoils was studied in NF-3 low speed airfoil wind tunnel of Northwestern Polytechnical University, based on three YD - blunt trailing edge wind turbine airfoils （35%, 40% and 60% relative thickness）. The results show that the leading edge roughness has a great influence on the performance of thick airfoils, resulting in a sharp decrease in the lift coefficient slope and the maximum lift coefficient, and the early separation of the flow at the trailing edge of the suction surface. |
