First stages of drop impact on a dry surface: asymptotic model

WitrynaThe water droplet absorbs the surfactant on the surface and the water’s surface tension decreases as it spreads, causing it to continue spreading after it would normally stop. On a clean surface without surfactant, a droplet of water will simply make contact, wet out and then cease moving. Witryna1 lis 2011 · After impact of a viscous liquid drop on a dry wall surrounded by a gas, the drop surface is highly deformed, leading to the formation of an axisymmetrical lateral lamella along the wall. A local asymptotic model for the potential flow and unsteady boundary layer flow is developed to describe the lamella dynamics at early stages … how much of my ram is being used right now

On some common features of drop impact on liquid surfaces

WitrynaSurface tension is the tendency of liquid surfaces at rest to shrink into the minimum surface area possible. Surface tension is what allows objects with a higher density than water such as razor blades and insects (e.g. water striders) to float on a water surface without becoming even partly submerged..
