A BOUNDARY ELEMENT ANALYSIS ON GALVANIC CORROSION PROBLEMS - COMPUTATIONAL ACCURACY ON GALVANIC FIELDS WITH SCREEN PLATES

To evaluate the computational accuracy of the boundary element method used to estimate the galvanic corrosion and cathodic protection in an actual and complex field, a galvanic field with a screen plate was analysed by using the single and multiple-region methods. It was found from two-dimensional analyses that the computated results obtained by both methods were well matched by reducing element size. Three-dimensional analyses were also done on cast iron and stainless steel cylindrical vessels with a screen plate. Good correspondence between the computated and experimental results were also obtained. © 1990.
