Friction-induced bubble edge curvature in flowing two-dimensional confined foams
Liquid foams are widely used in industrial processes, yet the interplay between foam structure and flow properties remains a topic of active research. This study investigates how friction forces and confinement in quasi-two-dimensional foams influence bubble shapes during flow, revealing anisotropic deformations and curvature of the films correlated to their orientation. Using experiments and a viscous froth-based model, we demonstrate a robust link between bubble curvature, anisotropy, and flow properties, providing new insights into the dynamics of foam flows under confinement.
