Non-Newtonian and non-isothermal effects in the gravity-driven draining of a vertically-aligned thin liquid film

Abstract

The drainage and thinning of liquid films are important in a variety of applications, such as in liquid and solid foam networks, relevant in the manufacture of metallic and ceramic foams, the food industry, processing in the petro-chemical industry, and the biological and life sciences. In a liquid foam network, there are gas bubbles separated by thin liquid lamellae. If one is interested in predicting the lifetime of a foam or its overall stability then, as a starting point, understanding the drainage within the lamella is important.
