Wettability and break-up of thin films on inclined surfaces with continuous and intermittent feed

Abstract

The conditions for complete wettability of dry or wet surfaces and film break-up have been studied. The minimum wetting rates and critical rate before break-up have been determined with various operation conditions, including liquid properties, temperature level and surface inclination. Two modes of liquid distribution at the top of the surface are considered, continuous and intermittent. The results are compared and discussed with reference to previous studies.
