The displacement of a liquid by an air bubble is a generic two-phase flow
that underpins applications as diverse as microfluidics, thin-film
coating, enhanced oil recovery, and biomechanics of the lungs. I will
present two intriguing examples of such flows where, firstly, oscillations
in the shape of propagating bubbles are induced by a simple change in tube
geometry, and secondly, flexible vessel boundaries that enable streamwise
variations of the channel depth suppress viscous fingering instability.
