| An electromagnetic device is proposed for the separation of inclusions from Aluminum. The device utilizes a magnetic structure that generates a current within the flow regime. The Electromagnetic force field exerts a pressure upon the inclusions which propels them towards a wall where they accumulate and are prevented from re-entering the stream.;The thesis presents two mathematical models which are used to reveal the fundamental mechanisms of inclusion removal from a liquid metal stream. The first of these is a simplified model which assumes a total independence between magnetic and flow fields. The second is a finite element model for fluid flow which is used to confirm the overall features of the simplified approach.;The main results of the thesis show that electromagnetic effects can be used for the removal of inclusions from a liquid metal stream. However, the magnitudes of excitation currents are high, and the geometry of the device fundamentally affects the efficiency of filtration. |
