Abstract

A closedmathematical description of the fields of velocities, concentrations, and temperatures on a contact cross-flow tray was obtained via simultaneous application of a two-dimensional system of differential energy, mass, and momentum transfer equations (written for liquid phase of a turbulent bubble layer with regard to gas interaction) and equilibrium and balance equations. The paper presents results of numerical solving this system and comparison with experimental data on the velocity field, concentration and temperature fields in distillation of various mixtures. Results of calculating the heat and mass transfer efficiency of bubble trays are also presented.
