摘要/Abstract

摘要： 以NREL Phase VI及其缩比风力机为研究对象，结合三维CFD数值模拟与二维翼型风洞实验，在低雷诺数下对Snel、Lindenburg、Du & Selig和Chaviaropoulos & Hansen 4种三维效应修正公式的修正效果进行了比较分析，结果显示修正效果各不相同，修正值普遍大于真实值，综合比较表明Du & Selig效果最佳，且Lindenburg、Snel、Chaviaropoulos & Hansen依次变差。修正效果与叶片尺度相关性从小到大的次序：在尖速比λ=5.39时整个叶展区域为Snel、Chaviaropoulos & Hansen、Lindenburg、Du & Selig；在λ=8.00时的整个叶展区域和λ=10.00时的叶中、叶片外侧区域均为Du & Selig、Lindenburg、Snel、Chaviaropoulos & Hansen；λ=10.00时的叶根区域为Lindenburg、Snel、Chaviaropoulos & Hansen、Du & Selig。

Abstract: Based on the NREL Phase VI and its scaled wind turbines, and combined with 3D CFD numerical simulations and 2D airfoil wind tunnel experiments, the correction effects of four three-dimensional effect correction formulas including Snel, Lindenburg, Du & Selig, Chaviaropoulos & Hansen in low Reynolds number are compared and analyzed. The results show that their effectiveness differs from each other while the correction value is generally larger than the real value. Specifically from the comprehensive comparison, Du & Selig formula demonstrates the best effect, and the performance can be ranked in descending order as Lindenburg, Snel and Chaviaropoulos & Hansen. Regarding the correlation between the correction effect and the blade scale from small to large when λ=5.39 in the whole blade area, it can be ordered as Snel, Chaviaropoulos & Hansen, Lindenburg, Du & Selig; when λ=8.00 in the whole blade area and λ=10.00 in the middle or outboard blade area, the order is Du & Selig, Lindenburg, Snel, Chaviaropoulos & Hansen; while when λ=10.00 in the root blade area, it goes like Lindenburg, Snel, Chaviaropoulos & Hansen, Du & Selig.
