| 摘 要： | 风力机气动特性主要由叶片贡献,但是处在流场下游的机身(包括机舱和塔架)对其也会产生影响。基于自由涡尾迹方法与面元法,得到了一个较为完备的风力机叶片与机身气动干扰的迭代计算方法。在该方法中,叶片用位于1/4弦线的一根升力涡线代替,结合叶片尾缘拖出的涡线建立自由涡尾迹模型,机身绕流模拟采用了一阶面元方法,将自由涡尾迹方法和面元法耦合模拟风力机主要气动特性。最后用该分析方法计算了NREL phaseVI风力机的气动特性,与实验结果进行比较和分析,验证了全耦合模型的有效性。

| Abstract: | The aerodynamic performance of a wind turbine mainly depends on its blades.It is also influenced by its fuselage including nacelle and tower.A free-wake/panel model coupled method is presented to investigate the aerodynamic interactions of wind turbine rotor and fuselage.In this method,a free-wake model is established in which the blade is replaced by a lift line set at a quarter chord position and vortex filaments extend from the trailing edge of blade.One-order panel method is used to calculate the potent... |
