Drop impact on thin film: Mixing, thickness variations, and ejections
J. Parmentier, Vincent Terrapon, Tristan Gilet
Abstract
The impact of a highly accelerated drop on a thin film of similar fluid is accompanied by the production of secondary droplets, while mixing occurs between the drop and the film. From high-speed imaging of laboratory experiments, we analyze the key aspects of this collision. Using an innovative colorimetry-based technique, we additionally deduce the size of the drop imprint in the film, the amount of water transferred from the drop to the film, and the total volume ejected away during the impact.
