Abstract

"Dynamic thin liquid films driven by an adjacent gas flow have been subject to many investigations due to the presence of such films in many engineering applications. More specifically though, the behavior of such films at a sharply expanding corner has received little attention, but can be observed in internal combustion engines, liquid atomizer systems, refrigerant flows in evaporators, and film drag over wetted surfaces. Efforts to validate computational models of the propagation and separation of films are limited by the lack of reliable non-intrusive techniques to measure and analyze dynamic film parameters. In this study, film propagation models and film separation models were validated separately using experimental film thickness and separation measurements. These experimental measurements were performed in an experimental facility that enabled controlled development of a shear-driven thin liquid film and allowed for subsequent film analysis"--Abstract, page iii.
