Locally Corrected Nystroem Discretization for Impressed Current Cathodic Protection Systems

摘要

A high-order locally corrected Nystrom discretization for analyzing impressed current cathodic protection systems is presented. Non-linear polarization curves are incorporated using a Newton-Raphson scheme. A Schur complement scheme is introduced to handle large domains with small electrodes. The methods are characterized in terms of error convergence and computation time by comparing to the analytic solution for a sphere and hemisphere.
