Аннотация: This paper proposes a mechanism of gas bubble formation in a down-flowing liquid film as a result of reduced pressure in circulation zones of threaded roughness recesses. Simulation modelling on the Comsol Multiphysics software was used to calculate circulation loops, liquid velocities, and pressure. Thus, the accepted of gas bubblПоказать полностьюe formation was justifying. We experimentally determined gas content along film thickness and its average value, and proposed an equation for calculating gas content along liquid layer thickness. The effect of gas content on the average thickness of a liquid film, as well as its heat and mass transfer, was confirmed.
