Abstract

Characterization accuracy in modeling of corrosion systems V.G. DeGiorgi", A. Kee\ E.D. Thomas' ® Mechanics of Materials Branch, Naval Research Laboratory, Washington DC, USA ^Geo- Centers, Inc., Ft. Washington, MD, USA ^Corrosion Facility, Naval Research Laboratory, ABSTRACT Boundary element techniques are well suited for the solution of LaPlace's equation in semi-infinite and infinite volumes. As in any computer modeling, issues must be addressed in the early stages of the analysis for the finished work to be an accurate evaluation of the system. The goal of the analysis must be clearly defined; preliminary and trend analyses often require less mesh refinement than detailed system evaluations. The work presented is a portion of a detailed evaluation of the impressed current cathodic protection system of an US Navy CG class surface ship. Physical scale model experimental data was available for direct comparison with computational results. The degree of mesh refinement required
