摘要
文章分别使用Wilson法和复合形优化法对水平轴风力机风轮进行了气动设计,对比德国XWEC-JACOBS600kw产品,前者设计的叶片弦长偏大,后者叶片尺寸与产品较吻合。为验证所设计的风轮性能,使用FLUENT软件进行了数值模拟,结果表明,Wilson法和复合形优化法设计的风轮功率误差分别为12.3和4.6,后者设计精度更高。
The known aerodyanmic design parameters of a German XWEC-JACOBS600kw horizontal wind turbine are given in Ref. 4. In section 1 of the full paper, we breifly introduce the Wilson method and the complex optimal method. Also in section 1, we point out that Xiao Jun et al developed the necessary program for complex optimal method. The calculated results, obtained with CFD (computational fluid dynamics) software FLUENT and shown in Figs. 2 and 4, show preliminarily that: (1) the chord length designed by the Wilson method is longer than that of the product while that designed by the complex optimal method is in good agreement with that of the product; (2) the complex optimal method is more accurate than the Wilson method, with less error of the designed power 4. 6% to 12.3%.
