摘　　要：根据当前计算流体动力学(CFD)数值模拟的研究,对风力机专用翼型S816的模型进行数值模拟,主要针对翼型的升阻特性、失速、流动分离等方面内容,研究了翼型升阻力系数随迎角的变化、翼型在非定常、定常数值模拟结果对比等因素对翼型气动特性的影响,并总结了相关规律。According to the types of CFD numerical simulation,the numerical simulation on the S816 special airfoil model for wind turbine is studied. The airfoil is simulated mainly for lift and drag charccterisstics, stall characteristics, flow separation and so on. With the changing of attack angle on airfoil result of comparison on unsteady and steady numerical simulation are studied, and lift and drag coefficient, and the got many significant conclusion.
