摘　　要：针对飞机飞行过程中机翼表面明冰结冰现象采用数值模拟方法建立了结冰模型。首先采用欧拉法构造了空气—水滴两相流流动模型,之后建立了考虑液态水回流效应的积冰模型。利用该模型模拟了明冰在NACA0012翼型上的生长过程,并将所得结果与NASA试验进行对比,获得了较好的一致性,证明该模型是合理的。According to the glaze ice accretion process on the surface of the airfoil during the air- craft＇ s flying, an icing model was established based on the numerical simulation approach. First, the air- droplets two -phase model was built using the Euler- based method. Then, considering the runbaek effect of the liquid water, the ice accretion model was proposed. This approach has been carried out to simulate the glaze ice accretion on the NACA0012 airfoil. The comparison with the experimental data was quite eonsentaneous, thus indicated that the current model is reasonable.
