[HTML][HTML] Numerical investigation of air mediated droplet bouncing on flat surfaces
H Shetabivash, A Dolatabadi - AIP Advances, 2017 - pubs.aip.org
A liquid droplet can bounce off a flat substrate independent of surface wettability if the impact
occurs at low velocities, ie, We of less than seven. In this case, the droplet spreads on a sub-
micrometer air layer and rebounds subsequently without any direct contact with the surface.
We have numerically investigated the process of air layer formation beneath the droplet. The
numerical simulations are validated using experimental results available in the literature
based on morphology of the droplet interface and thickness of the air layer. Numerical …
