摘　　要：在传统圆弧形风帆和NACA翼型的基础上,针对船用助航风帆的特点提出一种改进型的风帆翼型,利用Fluent软件,采用标准k-ε模型对传统圆弧形帆、NACA翼型和改进翼型在5-20 m/s、0-90°不同流速和不同攻角下翼型的空气动力特性进行了数值模拟计算,获得了相应的升力系数和阻力系数以及升阻比,证明其升力和阻升比均比传统圆弧形风帆有很大的提高.On the basis of traditional arcing sail and NACA airfoil,an improved sail airfoil is proposed according to the characteristic of sail-assisted equipment. The dynamic characteristic of traditional arcing sails,NACA airfoil and proposed airfoil are simulated with Fluent software based on standard k- ε model for different wind directions from 0 to 90°and different wind velocity from 5m / s to 20 m / s. Lift coefficients,drag coefficients and lift-todrag ratio were calculated. The results of numerical simulation showed that the proposed airfoil sail had bigger lift force and lift-to-drag ratio than traditional arcing sails.
