Numerical Investigation on Aerodynamic Performance of a Back-Swept Wind Turbine Blade

Keywords： wind turbine blades , back-swept , numerical simulation

采用商用软件FINETM／Turbo，以2．5MW风力机DF90风轮叶片为原型，在确认数值方法的基础上，将中叶展以上做后掠变型，进行三维定常数值模拟研究，讨论了后掠叶型对叶片气动特性的影响，并提出了一种定义后掠叶片静压系数的方法。

Numerical investigation of the steady and viscous flow around a back-swept blade was carried out by using a commercial software FINETM/Turbo. A 2.5 MW wind turbine DF90 was chosen as the baseline and was used to verify the numerical method. On this basis, the back-swept blade was assumed with sweeping back the planform at the outboard region. The influences of the back-swept planform on the aerodynamic performance were analyzed in details, and a method was proposed to define the static pressure coefficient.
