Abstract

A mathematical model has been developed to describe the electromagnetic and fluid flow phenomena and the inclusion particle motion in an electromagnetic separation process in which the electromagnetic force field is produced by induction from a time-varying magnetic field. The technique of mutual inductance was used to calculate the electromagnetic force field, while the laminar Navier-Stokes equations and the momentum equation of the particle were used to represent the fluid flow field and the particle history in the system. On the basis of the model it is possible to predict the range of the particle size which can be removed from the melt in terms of the basic process variables. The model is demonstrated for the prototype system developed at Oak Ridge National Laboratory.<>
