空气动力学分析是由两个变量的双致动器盘理论模型的Darrieus风力涡轮机。双多流管模型与恒定和可变的干扰因素，包括二次效应，检查Darrieus转子。二次效应的影响，即叶片几何形状和型线类型、旋转塔以及支柱和气动扰流器的存在，是相对显著的，特别是在高叶尖速度比时。作为最大角函数的诱导速度的变化允许相对于假定的恒定干扰因子更准确地计算转子顺风区上的气动载荷。将理论结果与Magdalen群岛风力涡轮机和Sandia型机器（直线/圆弧形状）的可用实验数据进行了比较。
An aerodynamic analysis is made of two variants of the two-actuator-disk theory for modeling the Darrieus wind turbine. The double-multiple-streamtube model with constant and variable interference factors, including secondary effects, is examined for a Darrieus rotor. The influence of the secondary effects, namely, the blade geometry and profile type, the rotating tower, and the presence of struts and aerodynamic spoilers, is relatively significant, especially at high tip-speed ratios. Variation of the induced velocity as a function of the aximuthal angle allows a more accurate calculation of the aerodynamic loads on the downwind zone of the rotor with respect to the assumed constant interference factors. The theoretical results were compared with available experimental data for the Magdalen Islands wind turbine and Sandia-type machines (straight-line/ circular-arc shape).
