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…
