Mathematical Models of Nonlinear Galvanic Polarization.

Abstract

The basic differential equation governing the conductive-current flow in an electrical continuum is analogous to the general heat-conduction equation. A series of simple steady-state electrochemical models were created using the COSMIC/NASTRAN finite-element program. The purpose of this study is to observe the behavior, physically and mathematically, of convective membrane boundary elements when assigned a nonlinear current-flow capability with respect to the local surface electric potential. Nodal potentials and current flows for a variety of boundary conditions and model configurations are given and modeling conclusions based on this analysis are presented. (Author)
