This paper discusses a simple model of electromagnetically stirred molten metal within a long cylinder, neglecting end effects. The radially‐dependent velocity profiles of the molten metal are calculated using the Prandtl mixing length model for turbulence. The paths of non‐conducting particles within the fluid are also computed numerically, under the influence of Stokes’ drag and a random force due to turbulence. The paths are calculated for a range of particle diameters and the general motion is observed. Copyright © 1999 John Wiley & Sons, Ltd.
