摘要：The effect of surface wettability on droplet impact on spherical surfaces is studied with the CLSVOF method. When the impact velocity is constant, with the increase in the contact angle (CA), the maximum spreading factor and time needed to reach the maximum spreading factor (t(max)) both decrease; the liquid film is more prone to breakup and rebound. When CA is constant, with the impact velocity increasing, the maximum spreading factor increases while t(max) decreases. With the curvature ratio increasing, the maximum spreading factor increases when CA is between 30 and 150 degrees, while it decreases when CA ranges from 0 to 30 degrees.
