Abstract
In this paper, a comparative analysis of schemes of heat and mass transfer devices of indirect evaporation type is carried out. These devices are a family of plane-parallel channels, in one of which the evaporation of water film takes place. Mathematical modeling of heat and mass transfer devices is based on solving a system of differential equations that represent the heat balance equations for each of the channels. Numerical studies are carried out in a wide range of input parameters: temperature t0 = 15÷50°C, relative air humidity ϕ0 = 20÷100%, and Reynolds number Re = 50÷1500. The assumed geometric dimensions of the channels are height H = 6 mm and length L 50H. The calculations are carried out at atmospheric pressure.
