Abstract

The use of a 3-D Poisson-Nernst-Planck (PNP) solver in a model for excess chemical potential (ECP) correction, for ion transport in biological ion channels, was investigated. To solve the 3-D system of PNP/ECP equations self-consistently, a decoupled feedback method was used. To test the PNP/ECP model, a simple 'hole-in-wall' problem was considered, consisting of a dielectric slab separating two electrolyte baths containing 1M NaCl under equilibrium conditions. The results show that when there is fixed charge density on the 'channel' walls, the PNP/ECP model shows a significantly lower density of the majority carrier.
