中文摘要：

本文利用CFD软件对NACA 4415翼型的失速特性进行二维数值研究,计算了来流攻角分别为-4度、0度、6度、14度、16度时翼型周围流场的速度分布和压力分布,并与二维P IV实验图片对比,掌握了NACA 4415翼型的失速特性,为加小翼风轮的三维动态数值模拟和P IV实验奠定基础和做出预测.

英文摘要：

In this paper,a two-dimensional numerical study on the stall of NACA 4415 airfoil is made by use of CFD.Pictures of the velocity contours,velocity vectors,and static pressure around the airfoil are given when it is submitted to five different attack angles and are compared with two-dimensional PIV experimental diagrams.As a good grip has been got on the stall characteristic of NACA4415 airfoil,the three-dimensional experiment on blades with tip vane can be carried out and the results can be predicted.
