“…High-gradient magnetic separation (HGMS) is a commonly used term in magnetic separations [33][34][35][36][37][38][39][40][41][42][43][44][45]. An HGMS device comprises of a bed of magnetically susceptible wires placed inside an electromagnet, as shown in Fig.…”

“…The first numerical work in this field has been developed in Japan by Okada et al [36] in 2005 for simulating the combined effect of fluid convection, particle diffusion, and magnetic forces on the motion of particles. Okada, et al applied a computational fluid dynamics (CFD) model to simulate HGMS process, because CFD models can solve a convection diffusion equation that includes the effect of fluid convection and diffusion on the motion of a scalar species like particles.…”

“…Therefore, the events such as saturation of the pores by particles, the detachment of the already captured particles or their recapture in the other active regions, the compression of the accumulated particles in the active regions by the time, and so on, must be evaluated. In terms of , filtration velocity of the cleaned liquid , the equivalent diameter of the capillary channel made of pores, and the viscosity of the suspension, the coefficients and can be approximately computed from (31) and the following equation, respectively: (35) wherein, by considering the approximate value of as (36) the filtration time that corresponds to the capturing process of the particles obtained by yields as (37) Relatively good agreement between the experimental and theoretical results given by Koksal [33] indicates that the described model here could reduce the gap existing between theory and practice and can be extensively developed so as to provide a general approach for obtaining magnetic filtration efficiency.…”

“…The reason is that the magnetic force of the particles is relatively smaller than their diffusion force. On the other hand, the magnetic chromatography system is a very useful device that uses the strong magnetic field gradients for separating ions or magnetic particles with different magnetic susceptibilities in a colloidal mixture [5]- [7].…”
