Implications of inhomogeneous distribution of concentration polarization for interpretation of pressure-driven [PDF]

open access: yes, 2016
A number of CFD studies have demonstrated that there is a considerable inhomogeneity of extent of Concentration Polarization (CP) over the membrane surface especially in spacer-filled feed channels. However, the consequences of this inhomogeneity for the
