基于边界元理论模型的舰船腐蚀相关电场衰减规律

摘要

The attenuation law of corrosion related electric field is studied based on the boundary element method. The result shows that the attenuation rate of the electric field transverse component and perpendicular component is larger than longitudinal component. Along with the increase of abeam distance, the attenuation rate of the longitudinal component and perpendicular component is reduced, but for the transverse component, the attenuation rate is increasing first, then reduced gradually. When the depth is increased, the attenuation rate of each component of electric field is reduced.%基于边界元理论,建立了舰船与腐蚀相关的电场模型,初步研究了舰船腐蚀相关电场在深海环境中随水平距离及深度的衰减规律.结果表明,电场横向分量与垂直分量随纵向距离的衰减速率要大于纵向分量.随正横距离的增加,电场纵向分量与垂直分量的衰减速率逐渐减小,而横向分量为先增大,后逐渐减小.正横距离一定时,电场各分量随深度的增加,衰减速率逐渐减小.
