Computational study of the optimum gradient magnetic field for the navigation of the spherical particles in the process of cleaning the water from heavy metals

摘要

The usage of magnetic spherical nanoparticles, coated with substances and driven to targeted areas in tanks, is proposed for cleaning the water from heavy metals. In the present paper, a computational study for the estimation of the optimum gradient magnetic field is presented in orderto ensure the optimum driving of the particles into the targeted area. The optimization of the gradient magnetic field rates' is verified with the particles' deviation from a desired trajectory. Using the above mentioned method, it was depicted that with the increase of the optimization parameters number, the particles' deviation from the desired trajectory is decreased.
