A method of analysing the electromagnetic field in induction devices

摘要

the electromagnetic field is analysed by combining the method of integral transformations, the boundary collocation method and discretization of the properties of the medium. The integral parameters of a rectangular in- ductor-cylindrical channel with liquid metal induction system are deter- mined. This approach enables one to avoid the use of special cylindrical functions and at the same time take into account changes in the angular velocity of the rotation of the metal over the channel's radius. The approach considered can be used when designing induction channel furnaces and electrical machines.
