Studies In Shallow And Thin-Film Flows, Md Mahmuder R. Faisal
Electronic Thesis and Dissertation Repository
The present study examines the influences of surface tension and wind direction in shallow or thin-film flow with the inclusion of inertial effect. In this present study starting with the fundamental equations (conservation of mass and momentum), an analytical method is introduced to determine the bottom stress at different position of a shallow or thin-film flow domain under the influence of oscillatory wind conditions. The novelty of this study is that the viscous and surface tension effects are considered in this study, whereas in most of the existing studies in a shallow or thin-film flow domain (a shallow tailings pond) …

A thin layer of film is developed on the surface of a substrate in the dip coating process where the substrate is initially immersed into the coating fluid and then withdrawn continuously from the coating fluid bath. In this study a two dimensional flow of the thin film for a Newtonian fluid is examined theoretically by dividing the film into three separate regions. A general formulation is developed for a thin film flow, which then simplifies for each region upon considering appropriate assumptions to each region. The influence of inertia and surface tension in the presence of gravity is investigated …
