Abstract

Abstract

In order to more systematically study the wake induced electromagnetic field caused during the navigation of the ship, based on the finite element method, the induced electromagnetic field generated by the wake motion of the Kriso container ship(KCS) was simulated by using magnetohydrodynamics, Maxwell equations, and other electromagnetic fields and fluid mechanics theories. The results show that the magnitude of KCS wake induced magnetic field has an obvious distribution law in the detectable range. The wake induced magnetic field has an extreme value in the direction of propagation, and its magnitude is related to the measurement position; the wake induced magnetic field increases with the distance to the extreme value and then gradually decreases along the propagation distance; the wake current density decreases along the propagation distance. The research in this paper can provide a reference for ocean electromagnetic exploration and ship tracking and positioning.
