摘　　要：以翼型为NACA0018升力型风机叶片为研究对象,基于CFD(Computational Fluid Dynamics)中的动网格技术对其在四个转速条件下进行了数值模拟,得到了叶片的扭矩系数、输出功率和风能利用系数的变化规律,计算结果表明:转速在200 r/min时叶片气动性能最佳,同时与滑移网格计算结果进行了比较,验证了其数值计算的可靠性。This paper takes airfoil for NACA0018 lift fan blades as the research specimen,they were performed by the numerical simulation based on the dynamic mesh technology of CFD in four rotating speed conditions,different behavior can be obtained,which are the blade torque coefficient,output power and wind power utilization coefficient.The results shown that blades have optimum aerodynamic performances under the rotating speed of 200 r/min.Comparing to the sliding grid computing results simultaneously,the reliability of numerical calculation can be verified.
