摘要
根据翼型俯仰运动规律,采用非结构动网格技术和不同的湍流模型对风力机的动态失速特性进行计算,其结果表明,动网格技术能有效计算振荡翼型的气动特性,较好地捕捉出风力机翼型在动态失速过程中涡的产生、脱落及湮灭过程;并得出SST k-ω湍流模型在运动翼型气动性能的计算方面有较高精度。
According to the law of pitching motion, using unstructured dynamic mesh and different turbulence models computed the dynamic aerodynamic characteristics. It showed that the dynamic mesh could effectively calculate the aerodynamic characteristics of oscillating airfoil, and could better simulate the generation, shedding and annihilation process of vortex when the airfoil of wind turbine dynamic stalling, and SST k-ω turbulence model has high precision in respect of the aerodynamic calculations for pitching airfoil.
