Escape from pinch-off during contraction of liquid sheets and two-dimensional drops of low-viscosity fluids

H Wee, AH Kumar, X Liu, OA Basaran - Physical Review Fluids, 2024 - APS
Liquid sheets are omnipresent in nature and applications. The cross sections of liquid
sheets are elongated two-dimensional (2D) drops the two ends of which contract towards …
