摘要

基于YD-系列3个大厚度钝后缘风力机翼型（相对厚度35%、40%和60%）,在西北工业大学NF-3低速翼型风洞开展粗糙敏感度对翼型性能影响的试验研究。结果表明,前缘粗糙对大厚度翼型的性能影响很大,造成升力线斜率和最大升力系数急剧减小,吸力面后缘流动的提前分离。

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.
