Interaction of the fluid film with the oncoming steam flow in the thermosiphon transport zone

Abstract

If the liquid film flows from the wall of the channel down and the core of the flow consists of one wind mixture of steam and small liquid drops, then this is called the flow mode of the steam-water mixture. In this case, a one-phase flow theory can be used, which provides the easiest way to study two-phase flows. Steam is a mixture of water, perceived as a quasicontinuum, for which the average properties of the flow are determined. The liquid film reacts with the approaching flow in the opposite direction of the phases with high humidification on their surfaces. In this case, external and internal problems of the flow of the hydrogen vapor mixture along the wall of the channel and the flow of the film will be considered. They can be expressed through the movement of velocities and phases on the surface of the film due to the increase in the interference between them.
