This paper is devoted to the numerical study of heat and mass transfer at evaporative cooling of a stream of a moist air in the horizontal channel, taking into account the final thickness of a film of water. Heat and mass transfer simulation is based on solving a system of differential equations for the laminar flow regime of air flow in a two-dimensional setting in the boundary layer approximation. Numerical studies are performed in a wide range of input parameters changes: temperature T 0 =10÷50 °C, relative humidity φ 0 = 0÷100 %, and Reynolds number Re = 50÷2000. The geometric dimensions of the channel are taken for height H = 6 mm and length L = 50 H . Calculations are performed at atmospheric pressure.
