Concentration boundary layer

A method to determine the critical concentration Rayleigh number in isothermal membrane transport processes was worked out. This method is based on equations which include the diffusive permeability coefficient, Tks; solution parameters (density, D; kinematic viscosity, <; diffusion coefficient, Dks

The development of concentration boundary layer (CBL) inside the hollow fibers, based on the experimental data from membrane-based solvent extraction of thallium (III) from chloride-containing acidic solutions with butyl acetate, was investigated. The experiments have been performed using three labo
