Abstract

Cathodic protection systems, such as those designed for ships, utilize material electrochemical properties to minimize corrosion damage. The extent of material interaction in the corrosion process is partially dependent on the resitivity of the surrounding medium. A medium with low resititvity, such as seawater, provides a greater degree of electrical connectivity than a medium of higher resistivity. In computational modeling studies seawater is typically represented as a uniform continuum with a single set of material properties. In reality, the resistivity of seawater varies with the amount of salt content and temperature. Salt content may vary for many reasons, including an influx of fre
