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 from 15 to 50 °С, relative air humidity from 20 to 100 %, and Reynolds number 50…1500. The calculations are carried out at atmospheric.


Keywords: evaporation cooling, wet bulb temperature, dew point temperature, efficiency, numerical modeling
