| 摘 要： | 本文以NACA23012翼型为研究对象，采用CFD软件模拟了结冰对翼型流场的影响。结果表明：结冰对翼型的气动性能有着明显的影响，尤其是在大攻角时，升力系数显著下降，而阻力系数则明显增加；对于光滑翼型和结冰翼型．计算值与试验值在‘定攻角范围内吻合良好：马赫数对两种翼型的升力系数和阻力系数随攻角的变化影响均比较小，雷诺数也一样。

| Abstract: | In this paper,CFD software is used to simulate the effect of icing on the airfoil flow-field,based on the airfoil of NACA 23012.Results show that:icing have obvious effect on the aerodynamic performance of airfoil,especially at the high attack angle,lift coefficient and drag coefficient change greatly;for the clean airfoil and iced airfoil,calculated values agree well with experimental data with at-tack angle stays in a certain range;Mach number and Reynolds number have a little effect on lift and drag coef... |
