Asymptotic Law of the Falling Liquid Film Form in Partial Wetting

Thickness of residual wetting film in liquid-liquid displacement.

Core-annular flow is common in nature, representing, for example, how streams of oil, surrounded by water, move in petroleum reservoirs. Oil, typically a nonwetting fluid, tends to occupy the middle (core) part of a channel, while water forms a surrounding wall-wetting film. What is the thickness of the wetting film? A classic theory has been in existence for nearly 50 years offering a solution...

Second Law Analysis of a non-Newtonian Laminar Falling Liquid Film Along an Inclined Heated Plate

The second law analysis of heat transfer of a non-Newtonian, laminar falling liquid film along an inclined heated plate is investigated. The upper surface of the liquid film is considered free and adiabatic. Velocity and temperature profiles are obtained analytically and used to compute the entropy generation number (Ns), irreversibility ratio (Ф) and the Bejan number (Be) for several values of...
