Nanofiltration Modeling Based on the Extended Nernst-Planck Equation under Different Physical Modes
Publié en 2008
The most successful nanofiltration models are those based on the combination of the Extended Nernst-Planck equation with the Donnan steric equilibrium. These models have been typically solved by using iterative procedures based on the Runge-Kutta method. Yet, such procedures present convergence problems in some cases.
In this paper, we present an implementation of the original Donnan Steric-partitioning Pore Model (DSPM) using COMSOL. Three different physical models were used and compared. The use of COMSOL benefits from the possibility of using stabilization techniques and the representation and analysis capabilities.
