Analyses of Various MHD Phenomena in EPM Application to Steelmaking Processes by Finite Volume Method
Applied technologies of magnetohydrodynamics(MHD)have been widely used in steelmaking based on their characteristics of clean and remote control of liquid metal.Generally,phenomena are quite complex and coupled among hydrodynamics,electromagnetism and thermodynamics,so numerical simulations play important roles in various applications of MHD for equipments design and control parameters decision.In the simulation,it is preferable to use one package calculation rather than coupled analyses such as the one between finite element method(FEM)and finite difference method(FDM)with the data conversion caused by different schemes.For the resolution,a three-dimensional finite volume approach for MHD is established based on scalar and vector potential and magnetic induction equation treated as transport equations.In this paper,results of the analyses of various MHD phenomena in EPM application to steelmaking process are described with some examples such as plasma heating and electromagnetic flow control tools.
