水平轴风力机专用翼型性能评估方法

An Evaluation Method of Wind Turbine Airfoil Performance

本文提出了风力机翼型完整的性能参数体系和相应的评估方法,并以此评估了CAS-W1翼型与DU翼型的性能特征。对翼型性能的评估侧重于失速特性、非设计点特性和翼型气动性能的稳定性。评估结果表明,相对于DU翼型,CAS-W1翼型系列设计点性能和非设计点性能较好,但是失速特性和性能稳定性需要优化。

This paper presents a wind turbine airfoil performance parameters system and corre- sponding evaluation method. Then the performance of the CAS-WI airfoils and the DU airfoils were evaluated. The emphasis of the evaluation is stalling characteristic, off-design performance and aerodynamic stability. Results show that compared with the DU airfoils, the CAS-WI airfoils had good design point, off-design performance while stalling characteristic and aerodynamic performance needed to be further optimized.
