管内阴极保护的数值模拟(Ⅱ)——有限差分法计算大口径管内的电位分布

Numerical simulation of cathodic protection inside pipes (Ⅱ)-calculating the potential distribution inside large-size pipes by using the finite difference method

采用有限差分技术对大口径输水管道管内阴极保护电位分布进行计算,理论值与实测值符合得较好。

The potential distribution of cathodic protection was calculated by using the finite difference method, the result shows that the theoretical value and the measured value are in good agreement.
