Abstract

Abstract:

Study on liquid metal motion in an applied magnetic field is of significance in theory and application. A model of initially static liquid metal in a uniform magnetic field is set up. A steady horizontal current is injected into the liquid metal and the 3D flow afterwards is numerically studied. Different magnetic field directions are considered in this work. Observations are given that electromagnetic (EM) field coupling leads to instability of the liquid metal, and the free surface is draped and distorted. A lot of minor liquid breakup masses and droplets are separated from the surface when the EM field is strong enough. Different strengths and directions of the EM fields can bring about quite different situations.

Key words: liquid metal flow, uniform magnetic field, steady current, numerical simulation
