Singularities in Soft Matter Systems
Vatsal Sanjay
When a liquid thread pinches off, its neck thins as it separates into two unconnected regions. Using continuum mechanics, we can predict that the neck reaches zero radius in finite…
Self-similar Worthington jets
José M. Gordillo, Javier RodrÃguez-RodrÃguez, Vatsal Sanjay
The paper studies how tiny bubbles bursting create fast, narrow jets (Worthington jets) by focusing inertia, showing that the jet’s size follows a self‑similar scaling law and that…
Confinement-Induced Suppression of Jet Drop Size by Bubble Bursting in Shallow Liquids
Zhengyu Yang, Vatsal Sanjay, C. Ricardo Constante-Amores +1
Bubble bursting is a major source of aerosol generation in a wide range of natural and industrial systems. While the resulting jet dynamics have been extensively studied in deep li…
Rheology of Two-Dimensional Dilute Emulsions
Thomas Appleford, Vatsal Sanjay, Maziyar Jalaal
The single droplet under shear is a foundational problem in fluid mechanics. In computational fluid dynamics, the two-dimensional (2D) formulation offers advantages in both computa…
How elasticity affects bubble pinch-off
Coen I. Verschuur, Alexandros T. Oratis, Vatsal Sanjay +1
The pinch-off of bubbles in viscoelastic liquids is a fundamental process that has received little attention compared to viscoelastic drop pinch-off. While these processes exhibit…
Holes in Sheets: Double-Threshold Rupture of Draining Liquid Films
Ayush K. Dixit, Chunheng Zhao, Stéphane Zaleski +2
Classical rupture is attributed to molecular (van der Waals) forces acting at nanometric thicknesses. Nonetheless, micron-thick liquid sheets routinely perforate far above the scal…
