Bursting bubbles in Herschel-Bulkley fluids: dynamics and jetting transitions
A. H. Ghaemi, Z. Yang, A. Huang +3
When a bubble rises to a free surface, its bursting dynamics in Newtonian fluids are governed by the interplay between viscous, capillary, and gravitational forces. In this work, w…
Stood-up drop to measure receding contact angles
Diego Díaz, Aman Bhargava, Franziska Walz +9
The wetting behavior of drops on natural and industrial surfaces is determined by the advancing and receding contact angles. They are commonly measured by the sessile drop techniqu…
Impacting spheres: from liquid drops to elastic beads
Saumili Jana, John Kolinski, Detlef Lohse +1
A liquid drop impacting a non-wetting rigid substrate laterally spreads, then retracts, and finally jumps off again. An elastic solid, by contrast, undergoes a slight deformation,…
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…
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…
Bouncing microdroplets on hydrophobic surfaces
Jamie Mclauchlan, Jim S. Walker, Vatsal Sanjay +4
Intuitively, slow droplets stick to a surface and faster droplets splash or bounce. However, recent work suggests that on non-wetting surfaces, whether microdroplets stick or bounc…
Implementation of integral surface tension formulations in a volume of fluid framework and their applications to Marangoni flows
Mandeep Saini, Vatsal Sanjay, Youssef Saade +2
Accurate numerical modeling of surface tension has been a challenging aspect of multiphase flow simulations. The integral formulation for modeling surface tension forces is known t…
To jump or not to jump: Adhesion and viscous dissipation dictate the detachment of coalescing wall-attached bubbles
Çayan Demirkır, Rui Yang, Aleksandr Bashkatov +3
Bubble coalescence can promote bubble departure at much smaller sizes compared to buoyancy. This can critically enhance the efficiency of gas-evolving electrochemical processes, su…
