existing magnetic, hydraulic and particle dynamic phenomena, the conception and the realization of a prototype
intended to purify flowing water by the extraction of contained ferromagnetic fine particles. A numerical approach
has been adapted and used in a 3D configuration. Such approach permits the taking into account the real effect of
the acting magnetic and hydrodynamic actions applied on the particles. The study of the particle behaviour in water
turbulent flow has permitted the identification of the parameters influencing on the separation performances. These
parameters are considered as optimization keys of the proposed device. The optimization was based on the
minimization of an objective function which is the distance between the central point of the capture element and the
capture site of a given particle with initial conditions chosen as a function of the flow and applied field
specifications. To implement the optimization approach, the Tabu search method has been used. The obtained
results have shown that the best capture is obtained by a separator with three capture elements spaced between them
by an angle of 120°. For a practical validation, a device has been realized and experiments have been achieved. The
flow regime is obtained by a pumping system. The capture elements are identical rectangular electromagnets. The
particles are injected through an opening made in the entrance of the channel. For a quantitative validation, the
particle motion and the captured particle build-up have been controlled by a camera. The quantitative validation has
been achieved by using a Hall effect sensing device.

Electro-techniqueTags : Aimant permanent éléments finis tambour optimisation par essaim de particules séparation magnétique Permanent magnet finite element drum particle swarm optimization magnetic separation مغناطيس دائم العناصر المنتهية أسطوانة عزل مغناطيسي تحسين سرب الجزيئات Index. décimale : 622 Electro-Technique Résumé :
The presented work in this thesis presents a contribution to the process of magnetic separation problems. This study based mainly on study and realization of an eddy current magnetic separator with a horizontal drum dedicated to ferromagnetic, diamagnetic, paramagnetic and conductive particles separation in dry and wet ways. A two-dimensional approach based on the model equations coupling governing the existing phenomena (magnetic, hydraulic and particle dynamics) has been developed and used to treat the magnetic separation problem. In order to achieve a successful separation, optimization of the proposed separator has been accomplished. This optimization requires the key parameters identification on which the separation depends. Such identification requires a resolution and analysis of the separation problem taking into account the existing phenomena evolution. The optimization carried out is based on the minimization of an objective function which is the distance between the end point of the separation and a chosen position in a way to take into account the specifications of the applied magnetic field and the velocities of the belt and liquid. For this, the Particle Swarm Optimization (PSO) method was used. In order to validate the approaches and the developed and implemented calculation codes on one hand, to verify the theoretical analysis carried out and the performances of the designed separator and to define the limits of its use on the other hand, experiments have been carried out in dry way. The device consists mainly of a drum with a succession of identical permanent magnets successively arranged with alternating polarity and driven by a motor controlled by a variable speed drive. Transport of the treated material is ensured by a conveyor belt running independently of the drum. The qualitative comparison of theoretical and experimental results showed a great concordance which validates the different approaches and performed calculations.Diplôme : Doctorat en sciences En ligne : ../theses/electrotec/OUI7556.pdf Format de la ressource électronique : Permalink : index.php?lvl=notice_display&id=11394 Optimisation du profil de l'induction magnétique Pour application de la séparation des particules non homogènes en voies sèche et humide.
