边界元法介绍及其在阴极保护领域应用

Introduction of Boundary Element Method and Its Application in Cathode Protection

数值模拟方法是对在实验研究方法遇到困难或难以展开时的补充。在对常见数值模拟方法的比较之后,得出边界元法在阴极保护领域的优势。边界元法作为一种新的数值模拟方法,其数学模型的建立需要一定合理的假设。数学模型的求解需要一定的边界条件,这些边界条件可分为三类,每一类别在相关环境中对应着一定的情况。在结果呈现中,由于参考电位的选取在不同行业有着不同的规定,因此在对相关标准进行对照比较时应搞清不同参比电极之间的电位关系并进行相应的转换。此外,还概括了边界元方法在阴极保护领域的使用现状。

Numerical simulation is the supplement of experiments in meeting difficulties, and advantages of the boundary element method （BEM） in cathode protection （CP） have been found in comparing with other common numerical simulation methods. The mathematical model has been introduced, and the present situation of the application of BEM software in CP has been discussed as well.
