Impact of a compound drop on a dry surface

Witryna13 mar 2024 · Drop impact on solid surfaces is encountered in numerous natural and technological processes. Although the impact of single-phase drops has been widely explored, the impact of compound drops has received little attention. Here, we demonstrate a self-lubrication mechanism for water-in-oil compound drops … Witryna1 lut 2024 · The distance between the impact surface and the drop generation system can be varied using a linear motor, allowing different impact velocities to be achieved. …
