Modeling of turbulent wake of surface vessel and measuring its induced magnetic field

Abstract

In this paper, the magnetic field induced by the turbulent wake of a vessel was measured and were compared with the results of modeling and calculations. It contains two essential steps: the first stage of solving the Navier-Stokes equations using Open Foam model and the second step measures the magnetic field induced by the vessel and calculation. two types of waves were studied in this paper, firstwind-driven wave and other turbulent wakes of vessel. Depth varied area in spring and winter measurements were performed. Both the turbulent wake velocity vector and magnetic field are expressed as superposition of sinusoidal waves. Modeling and measurement results show that the magnetic fields produced by wind waves or a typical size body moving at moderate speed are on the order of Nano-Tesla near the sea level depends on vessel speedand physical properties of seawater.
