Experimental Investigation of Magnetic Particle Transport in a Circular Minichannel in a Constant Magnetic Field

Abstract

Experimental investigation of the deposition of nanoparticles in a circular channel in a constant magnetic field has been carried out. The dynamics of growth of nanoparticles deposits on the channel walls depending on the Reynolds number and magnetic field strength has been studied in the experiments. The influence of magnetic field on pressure drop at different Reynolds numbers has been investigated. Characteristic profiles of the zones of nanoparticles depositions have been obtained for the first time; the sizes of the deposition areas and the rates of their formation depending on the Reynolds numbers, magnetic field strength and time have been determined.
