Hartmann flow in an annular channel

Abstract

Flow at high Hartmann number along the annular channel between two nonconducting cylinders of circular cross-section is examined. The core is divided and wakes appear at the boundaries of the various regions. In §§ 1-4 the case in which the cylinders are concentric is studied. In §5 the cylinders are eccentric, and it is shown that in this case there is a net flow of current around the annulus.
