海水中电偶极子电场分布有限元分析

Finite Element Analysis of Electric Fields in HED in Sea Water

利用高斯定律从理论上分析了等势小球和点电荷的电场分布的一致性,利用有限元方法推导出海水中静态和时谐电偶极子的电场有限元方程,通过对有限元方程的求解计算得到海水中任意场点的电场值。利用matlab建立了静态电偶极子模型,并比较、分析了其误差,结果表明,有限元电偶极子模型具有良好的远场效果,对计算海水中电偶极子电场分布具有很好的指导作用。

This paper analyzed the uniformity of electric fields between the isotonic ball and the point electricity charge.We described the fields by finite element functions for both the static HED and the time-harmonic HED,and solved the functions to get the electric fields everywhere in the deep sea.We analyzed the error by comparing with the model build by matlab.The emulative computation is given to demonstrate that model has an extremely high accuracy.
