Abstract: | Some experimental results of studying mass transfer during the evaporation of a liquid film from the surface of flat-plate and corrugated perforated packing into an air flow have been presented. An empirical equation for calculating the average coefficient of mass transfer with allowance for the effect produced by temperatures of heat-transfer agents, their physical properties, and flow rates, as well as the geometrical dimensions of a packed bed, on the mass-transfer process has been given. |
