| 摘 要： | 利用SST湍流模型,求解雷诺平均Navier-Stokes方程数值模拟螺旋桨粘性绕流。为了实现桨叶的相对运动,采用了滑动网格技术,即将计算区域分为静止区域和随桨叶一起运动的旋转区域。以课题组设计的1.2 m螺旋桨为例,分别对不同风速下的桨叶粘性流动进行了非定常数值模拟,计算得到的螺旋桨气动特性与实验值吻合良好,证明了方法的正确性。

| Abstract: | In this paper,the Reynolds-averaged Navier-Stokes equations are solved to simulate the viscous flow around a propeller,and SST turbulence model is used.Sliding Mesh Method is employed to imitate the rotating movement of the propeller.The mesh is divided into 2 zones:the stationary zone,the rotating zone moving together with the propeller.Based on a propeller model designed by our work group(diameter=1.2 m),we simulated the viscous flow around the propeller under different free stream velocity,and got the aerodynamic performance of the propeller.The computation results show good agreement with the experiment results. |
