摘要

•CFD modelling of concentration polarization effects in gas separation membranes.•Classical 1D models are shown to overestimate the efficiency of emerging membranes.•Development of an improved 1D model accounting for concentration polarization effects.•The improved 1D model and CFD results match over a wide range of operating conditions.•This generic tool opens the way to an easy design approach of membrane separations.
