Opposite-current flows in gas-liquid layers - III. Non-linear mass transfer

A theoretical analysis of non-linear mass transfer kinetics based on simila rity variables method for a gas-liquid opposite-current flow in the conditi ons of large concentration gradients has been done. The obtained numerical results for the energy dissipation in laminar boundary layers with flat pha se boundary and mass transfer rate are compared with analogous results for co-current flows. The ratio between the mass transfer rate and energy dissi pation is determined. The induced secondary flow in the gas phase influence s mass transfer kinetics significantly when the interphases mass transfer i s limited by the mass transfer in gas phase.
