abstract = {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. W. Park, M. Brito,
