520 _ _ |a The similarity solution of a boundary layer has been frequently applied to the modeling of concentration profiles of dispersions in the case of cross-flow ultrafiltration in a cylindrical membrane pipe. The main advantage of the similarity framework is to express the advection- diffusion equation in the boundary layer as a set of ordinary differential equations with given transport properties such as the concentration-dependent diffusion coefficient and the suspension viscosity. It is a challenging task, however, to extend the similarity framework to the time development of the concentration polarization (CP) and fouling layers, especially when a complex membrane geometry is considered. In this study, we present a finite element analysis of the time-developing CP and membrane cake layers which we compare with the standard similarity solution [1]. The transport properties required as input to the finite element and similarity calculations are determined and discussed for charge-stabilized suspensions of impermeable particles[2], non-ionic microgels[3], and ionic microgels with concentration- dependent radii [4].[1] G.
