A Maxwell-Stefan-Gouy-Debye model of the concentration profile of a charged solute in the polarisation layer

摘要

Based on the Maxwell-Stefan equation and the Gouy-Chapman model(with the Debye-Huckel approximation),this paper gives an analytical equation to describe the concentration profile of a charged solute in the concentration polarisation layer in terms of three dimensionless numbers(the Debye number,the Nernst number,and the boundary layer Peclet number).
