Abstract: In this work, we present a 3D approach for the
optimization of the capture element for an open-gradient magnetic separation
(OGMS) used for the purification of flowing liquids in a channel of small
diameter D = 2.5 × 10-2 m. This optimization is concerned with
the research of the capture element design and the excitation current that
allow the separation of ferromagnetic particles of fine size Rp =
3 × 10-5 m. The proposed approach is based on the minimization of
an objective function which is the distance between the particle capture
site and the central point of the capture element assumed to be the perfect
capture site. To obtain the particle capture site we have computed its
behavior where the important magnetic and hydrodynamic applied forces have
been taken into account. To perform the minimization of the objective
function, we have applied the Tabu search method. To validate the obtained
results, experiments have been performed on a flowing water containing
particles of iron. Such validation has dealt with the verification of the
capture site and the quantification of the volume of the separated particles buildup.
Keywords: Interdisciplinary applications of physics, magnetic separation, magnetic device characterization, particle dynamics, optimization.
