Effect of electrolyte velocity distribution on cathodicprotection of marine structures

将流场分析和电位场分析结合起来，分析绕流速度对海洋金属结构物表面阴极保护电位的影响，从而为给出更合理的阴极保护电位的计算方法提供依据．利用边界元法研制了流场分析和电位场分析通用程序ＰＣＢＥ，可计算有限域、无限域或半无限域问题．对圆柱绕流问题进行了计算．不同方案计算结果表明，表面介质流速对阴极保护电位的影响是明显的．

The effect of electrolyte velocity on electropotential distribution on marine structures under cathodic protection is investigated by using boundary element method. A boundary element program PCBE has been developed for the analysis of infinite and semiinfinite problems. Numerical analysis of cylinder diffraction problem was made. Numerical results show that the electrolyte velocity distribution has marked effect on cathodic protection of marine structures.
