Abstract
In this paper the turbulent flow generated in a cylindrical container by a low-frequency rotating magnetic field is considered. The rotational part of the electromagnetic body force is steady and axisymmetric, driving an azimuthal swirl flow. It is shown that curvature effects are negligible near the wall of the containing vessel and consequently the velocity profile in that region has the standard logarithmic form. Extrapolating this profile to the core allows an estimate of the core angular velocity to be made. This estimate is consistent with published experimental data and with the results of a more complex two-parameter closure model. MST/207
