Fragmentation versus cohesion

E Villermaux - Journal of Fluid Mechanics, 2020 - cambridge.org
Capillarity is the familiar manifestation of the cohesion of liquids. Since Laplace (Traité de
mécanique céleste, vol. IV, supplément au livre X: Sur l'action capillaire, 1805, pp. 1–65), we …

Cavitation bubble dynamics inside a droplet suspended in a different host fluid

S Li, Z Zhao, AM Zhang, R Han - Journal of Fluid Mechanics, 2024 - cambridge.org
