Antibubbles dynamics: the drainage of an air film with incompressible interfaces
An antibubble is a spherical air film that is immersed in a surfactant mixture and drains under the action of hydrostatic pressure. A dynamical model of this film is proposed that accounts for the surface shear viscosity effects in the case of incompressible interfaces, which apply for surfactants whose adsorption rate is much larger than convection rate and at concentration much above the cmc. Our model show that the lifetime of antibubbles in this case increases with surface shear viscosity, whose value is measured independently, all in agreement with experimental measurements.
