Oscillations of Bubbles Attached to a Capillary: Case of Pure Liquid
Result description
An oscillating bubble attached to a tip of a capillary is used for probing interfacial properties of liquids containing surface-active agents. Nevertheless, available theories even for the case of pure liquid are not satisfactory. In this contribution, we therefore present results of a linear inviscid theory for shape oscillations of a spherical bubble, which is in contact with a solid support. The theory allows determining eigenmode oscillations, but also response of the bubble shape to a motion of itssupport or to volume variations. Present theory covers also the cases previously analyzed by Strani and Sabetta (J. Fluid Mech., 1984) and Bostwick and Steen (Phys. Fluids, 2009), and it can be applied to both bubbles and drops. The theory has been compared to experiments.
