Numerical Simulation for Electric Field of Cathodic Protection of the Bottom Strengthening Plate of Instant Water Heater
摘要
Abstract
Objective]Aiming to design the impressed current cathodic protection system for the bottom steel plate of a constant water heater and to obtain the uniform electric field dis-tribution.[Methods]The finite element method was used to calculate electric field from ca-thodic protection of the strengthening plate based on different arrangements of auxiliary an-odes.[Results]When the auxiliary anodes being vertical to the steel bar were placed at 4/9 of the heater height,the potential began to be uniformly distributed.When the anode being parallel to the steel bar were placed at 1 1/18 to 13/18 of the heater length,the potential dis-attenuating phenomenon about potential.[Conclusion]So two auxiliary anodes were enough and economic.The anodes were preferably placed in a rectangular shape with specific coordi-nates.According to the attenuating curve,potentials of two ends can be adjusted to meet the requirement of standard.关键词
