Hydrodinamics of liquid film on cylindrical surface

Abstract

A theoretical study of the film movement of the liquid phase on the surface of a permeable cylinder under the influence of the mass forces of gravity and the swirling gas flow has been carried out. The differential equations of motion were determined for the first time, the exact solutions for the velocity components provided adhesion film on the surface of permeable cylinder and equality of shear stresses at the interface were calculated to determine the thickness of the film and its pressure on the cylindrical surface. Theimpact of the outflow of the liquid phase on the hydrodynamics of film flow was analyzed. The resulting mathematical model allows taking into account the hydrodynamics of the film during the filtration, separation and heat exchange processes.
