Numerical simulation of a falling droplet of liquid metal into a liquid layer in the presence of a uniform vertical magnetic field

Abstract

Dynamics of a falling droplet of liquid metal into a horizontal liquid layer in the presence of a uniform vertical magnetic field is numerically studied. Non-dimensional governing equations for an axisymmetric cylindrical coordinate system, which can simulate incompressible, immiscible two-phase flows like bubble, droplet and free-surface flows, have been derived and solved numerically with a finite difference method using the HSMAC algorithm. The numerical results reveal that the electromagnetic force simply opposes spreading of the disturbance after collision. © 2005 ISIJ.
