本文采用均匀多流管模型和多流管模型,建立了基于Troposkien曲线的Φ型垂直轴风力机气动性能的计算方法和程序。在多流管模型中加入了附加阻力系数修正和动态失速修正,提高了计算精度。分析了流管数目对流管模型计算结果,以及实度和高径比对Φ型风力机空气动力学特性的影响。
A method for calculating the aerodynamic performance of the Troposkien curvedΦtype vertical axial wind turbine with uniform multiple streamtube and multiple streamtube models is proposed in this paper.In order to improve the accuracy of multiple streamtube model,additional resistance coefficient and dynamic stall modification are introduced into the implementation.Influences of the number of streamtubes on the calculated results,the blade solidity and the height to diameter ratios on the aerodynamic performance have been analyzed.
