摘要：

A method for predicting permeate fluxes in laminar ultrafiltration of macromolecular solutions was proposed. The method is based on a modified osmotic pressure model with the mass transfer coefficient estimated from the Leveque solution and the diffusion coefficient evaluated at the mean concentration of the concentration polarization layer. The validity of the method was tested by comparing predictions with experiments. (C) 1998 Elsevier Science B.V.
