Particle-tracking within turbulent cylindrical electromagnetically-driven flow

Abstract

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.
