Drop impact onto a thin film: Miscibility effect

N Chen, H Chen, A Amirfazli - Physics of Fluids, 2017 - pubs.aip.org
In this work a systematic experimental study was performed to understand the process of
liquid drop impact onto a thin film made of a different liquid from drop. The drop and film …
