It is proposed to study the migration and aggregation of particulate impurities in liquid metal systems, and the manner in which these processes may be influenced and controlled by means of applied electromagnetic fields. Lagrangian techniques, which have been used for the study of chaotic particle paths in unsteady two-dimensional flows and in steady three-dimensional flows, will be developed for solid particle impurities whose density and conductivity differ from that of the surrounding liquid metal, and which are subjected to net forces, and possibly couples of electromagnetic origin. The aim is to understand the manner in which these electromagnetic forces can influence such processes as :the migration of particles across flow streamlines; the trapping of particles in vortical regions; the agglomeration of particles in close encounters; and the spread of impurities due to turbulent diffusion. The governing dynamical system is fourth-order for 2D flows, sixth-order for 3D flows, and is in general non-autonomous and non-Hamiltonian.The study is motivated by the need to maintain increasingly high levels of purity in casting and melting processes in metallurgical industries, eg steel and aluminium. The control and removal of impurities is an essential requirement in the efficient production of high quality metals and alloys. The project will contribute to a better understanding of the fundamental magnetohydrodynamic processes involved in these operations.
