Non-linear mass transfer and Marangoni effect

The comparative analysis of the influence of the effect of non-linear mass transfer and the Marangoni effect on the mass transfer kinetics has been do ne. Co-current two-phase (gas and liquid) flow in the laminar boundary laye r along the flat phase surface is considered. One of the components of the first phase reacts with a component of the second phase. The chemical react ion rate is of first order. The heat effect from the chemical reaction crea tes a temperature gradient, i. e. the mass transfer together with a heat tr ansfer can be observed. Non-linear mass transfer and Marangoni effect are r esults of a large concentration gradient and interfacial tension gradient. The data for heat and mass transfer coefficients are obtained.
