摘要
介绍了阴极保护边界元数值仿真发展现状和技术方法。建立了平台导管架的模型,并在模拟实验水池中开展了实海条件下的阴极保护试验。在建模的基础上,运用边界元技术求解了该导管架模型在阴极保护状态下的电化学腐蚀控制方程,给出了电位分布和电流密度分布,仿真计算结果与模拟试验测量结果吻合很好。
Advances and detailed process of offshore cathodic protection modelling using the boundary element method are introduced. A miniature model of offshore jacket is built and used to test the CP performance in a seawater pool which can simulate tidal behevior of the sea. Based on the model, BEM is employed to sovle the governing equations under cathodic protection. Solutions of both potential and current density ditribution are presented and compared with the actual potential measurement of the miniature model offshore jacket, which shows a good agreement between them.
