NONLINEAR MASS-TRANSFER AND MARANGONI EFFECT IN GAS-LIQUID SYSTEMS

The comparative analysis of the influence of the effect of non-linear mass transfer and the Marangoni effect on the mass transfer kinetics a nd the hydrodynamic stability are done. Co-current gas and liquid flow in the laminar boundary layer along the flat phase surface is conside red. One of the components of gas is absorbed by the liquid and reacts with a liquid component. The chemical reaction rate is of first-order . The heat effect from the chemical reaction creates a temperature gra dient, i.e. the mass transfer together with a heat transfer can be obs erved. The data for heat and mass transfer coefficients are obtained. The critical Reynolds numbers, corresponding wave velocities, and wave numbers are obtained. (C) 1997 Elsevier Science Ltd.
