Thin liquid films are considered to be the basic structural elements of foam and emulsion systems. Consequently, the structure and stability of macro-dispersions are highly dependent on the dynamic structure formation and stability of a single, thin, curved film between unequal-sized bubbles and dro

โฆ Synopsis
Analytical equations for the radial drainage of uniform thin viscous films are obtained in terms of the variation in surface velocities and velocity gradients with position and time. These allow the effect of circulation in the adjacent phases and radial surface or interfacial tension gradients to be allowed for. The resultant coalescence time (t_{\mathrm{c}}) may be estimated from the equation

Drainage of a partially mobile thin liquid film between two deformed and nondeformed gas bubbles with different radii is studied. The lubrication approximation is used to obtain the influence of soluble and insoluble surfactants on the velocity of film thinning in the case of quasi-steady state appr
A mathematical model is formulated and solved numerically describing the local thinning of liquid films between a solid/ liquid interface and a fluid/liquid interface with a variable surface concentration of an insoluble surfactant. Reynolds lubrication approximation is used. The initial excess surf
Drainage of a mobile, symmetric, plane parallel thin liquid film between two gas bubbles is studied. An analytical solution for the rate of thinning of such a liquid film with an insoluble surfactant and having both film elasticity and surface viscosity is presented for the first time. Analysis is e
