Studying on Shielding Effect in the Sacrificial Anode Cathodic Protection System

Abstract:

In order to study “shielding effect” problems of sacrificial anode cathodic protection system in the ballast water tanks, two sets of experiments, the “block-type shielding effect” and the “absorbed-type shielding effect” are carried out by changing the clapboard height and the distance from the upper surface of sacrificial anode to the copper tube, and corresponding numerical simulations are carried out. Both of the experimental data and the numerical simulation results illustrate the two kinds of “shielding effect” as mentioned above, and according to which, both the two kinds of “shielding effect” should be surely taken into account in sacrificial anode cathodic protection system for a ballast water tank.
