Abstract
A novel method to study the flow characteristics of thin liquid films draining down an oscillating vertical surface is presented. A Mach-Zeh nder interferometer was used to measure changes in film thickness and parameters such as local gradient at the film surface were derived. Th e measurements were found to be consistent with previous theoretical p redictions.
