A comprehensive understanding of the inter‐bubble dynamics and the cluster formations in
non‐Newtonian fluids is pivotal for chemical and biomedical engineering applications. In …

We consider the buoyancy-driven rise and interaction between two coaxially placed bubbles
of equal size and constant volume that are initially stationary inside an elastoviscoplastic …

Experiments are reported that explore the onset of motion of bubbles in a model yield stress
fluid, Carbopol gel. Starting from a trapped spherical bubble in a gel, the yielding limit for the …

A gas bubble sitting at a liquid–gas interface can burst following the rupture of the thin liquid
film separating it from the ambient, owing to the large surface energy of the resultant cavity …

The motion of air bubbles within a liquid plays a crucial role in various aspects including
heat transfer and material quality. In the context of non-Newtonian fluids, such as …

We study theoretically the stretching dynamics of a yield stress material that exhibits both
elastic and viscoplastic behavior. The material is confined between two coaxial disks …

Elastoviscoplastic (EVP) fluids, which exhibit both solid-like and liquid-like behaviors
depending on the applied stress, are critical in industrial processes involving complex …

Bubble bursting and subsequent collapse of the open cavity at free surfaces of contaminated
liquids can generate aerosol droplets, facilitating pathogen transport. After film rupture …

The sedimentation dynamics of a prolate spheroidal particle in an unbounded
elastoviscoplastic (EVP) fluid is studied by direct finite element simulations under inertialess …

Ideal viscoplastic models present an inherent discontinuity at the yielded/unyielded
interface, which poses great numerical difficulties. In this work, the recently proposed …
