Abstract
The rotation of a thin layer of an electrically conducting fluid partially filling a channel of annular cross section inside a stator with a rotating field is considered with neglect of friction at the channel end. For a turbulent flow, when the fluid velocity is much smaller than the field velocity, the shape of the free surface, the velocity profile, and the losses in the electrically conducting fluid are shown to be dependent on the magnitude of the rotating field with allowance for the transverse edge effect. The calculation is compared with experiment.
