Modeling of conjugated heat and mass transfer during film desorption

Abstract

The heat and mass transfer in the process of desorption on a free falling liquid film of the LiBr-water solution is analyzed analytically. The dependences of the Nusselt number on the surface on the longitudinal coordinate downstream of the film were found, and the thickness of the film, which changed due to desorption, was determined.The problem was investigated for different values of Froude and Peclet numbers, for different values of initial film thickness.
