Drop impact Drop impact occurs when a liquid drop strikes a solid or liquid surface. The resulting outcome depends on the properties of the drop, the surface, and the surrounding fluid, which is most commonly a gas. == Drop impact on a dry solid surface ==
When a liquid drop impacts a dry solid surface, it generally spreads on the surface, and then will retract if the impact is energetic enough to cause the drop to spread out more that it would generally spread due to its static receding contact angle. The specific outcome of the impact depends mostly upon the drop size, velocity, surface tension, viscosity, and also upon the surface roughness and the contact angle between the drop and the surface.〔Rioboo, Romain, Cameron Tropea, and Marco Marengo.
