| 摘 要： | 采用一种适用于分析机翼结冰过程的数值模拟方法，该方法在飞机结冰气象条件下采用计算流体力学（Computational Fluid Dynamics，CFD）对机翼流场进行计算，获得流场中二维机翼翼型的水滴撞击特性，并遵循质量和能量守恒方程，计算出机翼表面的结冰量，预测出机翼的积冰形状。所得冰形与文献中的试验数据吻合良好，表明数值模拟方法有效。另外还分析了结冰对机翼升力、阻力和压力系数的影响，其结果可以指导飞机机翼防／除冰系统的设计研究

| Abstract: | A numerical simulation approach is presented to simulate the ice accretion process on a two-dimensional airfoil,which uses Computational Fluid Dynamics(CFD) software FLUENT to predict the flow field and the droplet trajectories.After computing the mass and energy equations,ice accretion shape is derived from the ice mass flux on the airfoil.The comparison between the results of this paper and the experimental data indicates that the approach is applicable and effective.Flight performances,including lift,dra... |
