Magnetic Field Analysis On A Cylindrical Matrix Of HGMS Through Conform Mapping

Abstract

Magnetic matrix plays a decisive role in the capture efficiency of high-gradient magnetic separation (HGMS) system. This paper took a parallel arranged cylindrical matrix for example,and put forward using conform mapping to calculate the magnetic field distribution in the matrix. After established the simplified two-dimensional analytical model, this paper promoted the procedure of magnetic field analysis through conform mapping,and then analyzed the magnetic field strength and magnetic traction force that derived from this method.The results were consistent with previous studies that mainly adopted Finite Element Method. The method also can be used to determin hydrodynamic drag force that affects the capture efficiency mainly. The study will contribute to further explore the capture mechanism of magnetic particles in high-gradient magnetic separation.
