Abstract

The problem is discussed of taking into account the viscous properties of a binary vapor-gas system in an analysis of diffusion fluxes during vaporization on the condition that the “accepting” gas is not absorbed by a vaporizing liquid. To answer the question of the correctness of using the Navier-Stokes equation together with the Stefan-Maxwell equation in this problem for taking into account the influence of walls on diffusion processes in fairly broad channels, it is suggested to experimentally measure diffusion fluxes of a vaporizing component in a diffusion chamber with parallel communicating channels and compare the measured fluxes with the calculation results.
