摘要
在NACA0006翼型和圆弧型风帆的基础上,针对船用助航风帆的特点设计出一种新型翼型风帆,并采用标准κ-ε模型,利用FLUENT软件对翼型在8个不同风向角下的空气动力特性进行了数值模拟计算,获得翼型风帆在8种不同风向角下的升力系数和阻力系数,并对计算风帆模型进行风洞试验,风洞试验得到的升力系数和阻力系数结果与模拟计算结果有较好的吻合,通过试验结果对比证明其升力系数比常规的矩形圆弧风帆有很大提高.
A new kind of airfoil sail is proposed in this paper based on NACA0006 aerofoil and circuldr-arc sails. The aerodynamic characteristic is numerically simulated with FLUENT software based on standard κ-ε model under 8 different wind directions. Lift coefficients and drag coefficients were calculated and wind tunnel experiments of the model were conducted. The result of lift coefficient and drag coefficient obtained by numerical simulation coincide with wind tunnel experiment data, which verified bigger lift force of the proposed aerofoil sail compared to traditional arcing sails.
