摘要: 建立了金属储罐底板外侧阴极保护电位分布的数学模型,采用混合控制的极化理论来描述阴极极化特性,利用FLUENT软件模拟了不同辅助阳极埋设方式下罐底外侧的阴极保护电位分布,并对不同阳极埋设方式下电阻率和罐径对电位分布的影响进行了对比,为罐底阴极保护电位分布效果的判定和阳极布置方式的选择提供了理论指导。

Abstract:The mathematical model of cathodic protection potential distribution on the exterior of tank bottom is established and cathodic polarization performance is described according to the mixed polarization theory. The cathodic protection potential distribution on the exterior of tank bottom under protection of different kinds of anode placement manners is calculated by FLUENT software and the effects of soil resistivity and tank diameter on potential distribution are studied and compared also. The results can provide theoretical guidance for determining cathodic protection effects and choosing anode placement manners.
