摘　　要：液滴撞击不同润湿壁面会产生不同的动力学行为,如粘附、反弹以及飞溅等,同时表面也会对液滴在壁面上的振荡行为有着重要影响。为探究壁面润湿性对液滴振荡行为的作用,利用VOF相界面追踪法对液滴撞击不同润湿性壁面的振荡特性进行了仿真模拟。仿真结果表明在其他条件相同下,壁面接触角增加,液滴最大扩展因子逐渐减小,平均振荡周期减小。The droplet impacting on different wetting surface will produce different dynamic behaviors,such as adhesion,rebound and splash.At the same time,the solid surface will also have an important impact on the oscillation behavior of droplet.In order to explore the effect of surface wettability on droplet oscillation behavior in a large time range,the oscillation characteristics of droplets impacting on different surfaces are simulated by VOF phase interface tracking method.The simulation results show that under the same conditions,both of the maximum droplet expansion factor and the average oscillation period decrease with the increase of contact angle of solid surface.
