Many biological surfaces of animals and plants (eg, bird feathers, insect wings, plant leaves,
etc.) are superhydrophobic with rough surfaces at different length scales. Previous studies …

Innovations in fluid mechanics have been leading to better food since ancient history, while
creativity in cooking has inspired fundamental breakthroughs in science. This review …

For steady flow past two stationary circular cylinders that are aligned in tandem with their
axes perpendicular to the flow direction, the wake pattern, vortex shedding frequency, and …

Marginal regeneration is the process at the origin of the thinner patches produced at the
bottom of vertical soap films and slowly rising to the top. It controls the film drainage, and …

For a flowing soap film with added surfactants, theoretically there exists symmetric elastic
waves due to the elasticity of the soap film that originates from the surface tension change …

The surface tension of flowing soap films is measured with respect to the film thickness and
the concentration of soap solution. We perform this measurement by measuring the …

In this paper, we investigate the thinning dynamics of evaporating surfactant-stabilised
surface bubbles by considering the role of physical-chemistry of solutions used in a liquid …

A quasi-two-dimensional shear layer is produced by merging two gravity-driven flows of
soap film at different average velocities. The Kelvin–Helmholtz instability dominates the …

Production, drainage, and stability of foam films, ie, films in contact with their menisci, are
fascinating problems that remain still unsolved. In this article, we propose to explore the …

We show the validity of using a flowing soap film system as a two-dimensional laboratory
model of flow past a circular cylinder at low Reynolds numbers through a novel combination …
