Eulerian method is employed to analyze the droplets impingement characteristics of NA-CA0012 at different speeds and in different meteorological conditions.The commercial software Fluent is used to calculate the air flow field,and UDS is applied to work out the water droplets phase control equation.The results show that local water droplets collect coefficient and water droplets collision increase as the flight speed and average droplet volume diameter increase and that liquid water content has little influence on the droplet impingement property.%基于欧拉方法分析了不同飞行速度和不同气象条件下 NACA0012机翼水滴撞击的特性，使用 Fluent 商用软件计算空气流场，并通过 UDS 模块求解水滴相控制方程。从计算结果分析得出：局部水滴收集系数及水滴撞击范围随飞行速度和平均水滴容积直径的增加而明显增加；液态水含量对水滴撞击特性影响不大。
