Nonstationary electrovortex flows in a long shallow channel with conducting fluid

This paper describes our investigations into the generation of the electro-vortex flow of a conducting fluid in a plane long layer in the unstable regime. In the context of the present problem we consider the velocity field and the amplitude and frequency of velocity oscillations of this flow. The pressure drop in the channel with inclined ferromagnetic plates induced by both the direct and alternating electrical currents is studied. The obtained results can be used in developing metallurgical devices having the maximum possible stability of the flow-rate.
