Numerical Investigations on Dynamic Stall Characteristics of a Finite Wing
研究了展弦比为8的有限翼展机翼的动态失速特性,以深入了解三维效应对流场结构、气动特性和俯仰阻尼的影响.首先,构建了计算流体动力学方法来模拟机翼的气动特性,采用有限体积法求解URANS方程,通过k-ω(Shear stress transport,SST)两方程湍流模型来考虑黏性效应.然后,采用上述CFD方法模拟了静态平直机翼和俯仰振荡尖削机翼的气动特性,数值结果与试验数据之间良好的一致性验证了CFD方法的有效性和准确性.最后,计算分析了有限翼展机…查看全部>>
The paper examines the dynamic stall characteristics of a finite wing with an aspect ratio of eight in order to explore the 3D effects on flow topology,aerodynamic characteristics,and pitching damping.Firstly,CFD methods are developed to calculate the aerodynamic characteristics of wings.The URANS equations are solved using a finite volume method,and the two-equation k-ω shear stress transport(SST)turbulence model is employed to account for viscosity effects…查看全部>>
