Reveals marangoni circulations influencing meniscus splitting during drying, indicating complex fluid dynamics in pectin dispersions.
Marangoni Circulations during Meniscus Splitting Meniscus splitting pattern emerges during drying of aqueous polymer dispersions in an open-top Hele–Shaw cell. In pectin dispersions, particle image velocimetry visualizes the evolution of Marangoni convection, revealing the significant bulk circulations beneath the seemingly calm interface. Confluence and bifurcation of the mass flow spatiotemporally shape the skin-layer densification.
