Thin liquid films are fundamental components in a variety of industrial processes including foam manufacturing and oil exploration. Improved understanding of the drainage is essential for accurate predictions of the stability and lifetime of a film. Numerous fundamental studies of thin films have been conducted in Scheludko-Exerowa cells, in which a biconcave foam or emulsion film is created by suspending a thin liquid film across a gas filled or liquid filled tube. Using optical probes, the film thickness can be measured as a function of time with high precision. In this paper, predictions of drainage times from the lubrication theory of Reynolds and the Manev-Tsekov-Radoev (MTR) theory are compared to experimental measurements obtained from numerous investigators. A semi-empirical equation consistent with MTR theory is described and is shown to be most consistent with a broad range of experimental data.
