Surfactant amplifies yield-stress effects in the capillary instability of a film coating a tube
James D. Shemilt, Alex Horsley, Oliver E. Jensen +2
To assess how the presence of surfactant in lung airways alters the flow of mucus that leads to plug formation and airway closure, we investigate the effect of insoluble surfactant…
Surface-tension-driven evolution of a viscoplastic liquid coating the interior of a cylindrical tube
James Shemilt, Alexander Horsley, Oliver Jensen +2
One mechanism for airway closure in the lung is the surface-tension-driven instability of the mucus layer which lines the airway wall. We study the instability of an axisymmetric l…
The interaction of multiple bubbles in a Hele-Shaw channel
J. S. Keeler, A. Gaillard, J. Lawless +3
We study the dynamics of two air bubbles driven by the motion of a suspending viscous fluid in a Hele-Shaw channel with a small elevation along its centreline via physical experime…
The engulfment of aqueous droplets on perfectly wetting oil layers
Callum Cuttle, Alice B. Thompson, Draga Pihler-Puzović +1
Place a droplet of mineral oil on water and the oil will spread to cover the water surface in a thin film -- a phenomenon familiar to many, owing to the rainbow-faced puddles left…
The life and fate of a bubble in a geometrically-perturbed Hele-Shaw channel
Antoine Gaillard, Jack S. Keeler, Grégoire Le Lay +4
Motivated by the desire to understand complex transient behaviour in fluid flows, we study the dynamics of an air bubble driven by the steady motion of a suspending viscous fluid w…
The influence of invariant solutions on the transient behaviour of an air bubble in a Hele-Shaw channel
J. S. Keeler, A. B. Thompson, G. Lemoult +2
We hypothesize that dynamical systems concepts used to study the transition to turbulence in shear flows are applicable to other transition phenomena in fluid mechanics. In this pa…
