Thermal antibubble
ORAL
Abstract
The impact of a droplet on a pool, again... Droplets of a volatile liquid are dropped on a hot pool of oil. The temperature of the pool is beyond the boiling temperature of the liquid that the droplet is made of. For a given set of parameters (impact height, droplet size, temperature of the bath), the droplet penetrates below the surface of the bath being protected by a thin film of vapor. This object reminds the antibubble case that is the opposite picture of a bubble: instead of having a spherical thin film of a liquid in a gas, the antibubble is a thin film of gas in a liquid.
