Abstract
The possibility of controlling the flow in an electrically conducting medium (liquid metal) by changing the phase difference of the linear induction machine has been experimentally studied. Phase A was determined at 0^°, phases B and C varied from 0^° to 360^° in steps of 36^°. A flat vertical layer of a gallium-zinc-tin alloy was considered. Different powering modes leading to formation of flows of different topologies of one to four vortices were obtained and described. It is shown that a change of the linear induction machine phase difference is an effective tool for controlling the flow of a conducting medium, which is suitable for solving the main problems of metallurgy, such are transport, heating, stirring and purification of impurities.
