摘　　要：为了更系统地研究船舶在航行过程中引起的尾流感应电磁场,文中以有限元法为基础,利用磁流体力学、麦克斯韦方程组等电磁场和流体力学理论,对KCS船舶尾流运动产生的感应电磁场进行仿真分析。结果表明:KCS船舶尾流感应磁场量级在可探测范围内有明显的分布规律;尾流感应磁场在传播方向上存在极值,其大小与测量位置相关;尾流感应磁场先随距离增大到极值,再沿传播距离方向逐渐衰减;尾流电流密度沿传播距离方向逐渐衰减。文中的研究可为海洋电磁探测及船舶跟踪和定位等研究提供参考。In order to more systematically study the wake induced electromagnetic field caused during the navigation of theship,based on the finite element method,the induced electromagnetic field generated by the wake motion of the Krisocontainer ship(KCS)was simulated by using magnetohydrodynamics,Maxwell equations,and other electromagnetic fields andfluid mechanics theories.The results show that the magnitude of KCS wake induced magnetic field has an obvious distributionlaw in the detectable range.The wake induced magnetic field has an extreme value in the direction of propagation,and itsmagnitude is related to the measurement position;the wake induced magnetic field increases with the distance to the extremevalue and then gradually decreases along the propagation distance;the wake current density decreases along the propagationdistance.The research in this paper can provide a reference for ocean electromagnetic exploration and ship tracking andpositioning.
