NUMERICAL AND EXPERIMENTAL INVESTIGATION OF LIQUID FILM MOTION ON AN INCLINED WALL
This paper presents some of the results from numerical isothermal 3D computations as well as experimental measurements of the liquid film flow down an inclined solid wall. Computational fluid dynamics (CFD) simulation including a two-phase (water/air) volume-of-fluid model with freesurface, and visualization of the liquid film using a high-resolution camera are conducted. The film response for different entrance flow rates and different conditions at the film-side boundaries is examined. The flow properties and quantities of interests are liquid-film thickness, the shape of the liquid-film surface, and the surface-wave development. The simulation and experimental results are compared showing an acceptable agreement.
