INCREASING THE EFFICIENCY OF MULTY-VARIANT CALCULATIONS OF ELECTROMAGNETIC FIELD DISTRIBUTION IN MATRIX OF A POLYGRADIENT SEPARATOR

An approach is proposed to carry out multivariate calculations of the magnetic field distribution in working gaps a plate polygradient matrix an electromagnetic separator, based on combination advantages two- and three-dimensional computer modeling. Two-dimensional geometric models computational domains are developed, which differ dimensions elements air gaps. To determine vector potential at boundaries two-dimensional domains, 3D experiment carried out. For this, three variants separator selected, size matrices. them, built, spatial intervals obtained numerical values investigated. The determination for all other by interpolation. used set boundary conditions 2D experiment. choice rational version lamellar substantiated, provides solution problem according criterion effective area area. Using method simple enumeration, variant structure with parameters selected. productivity increased 3–5 % same efficiency extraction ferromagnetic inclusions comparison basic device
