A study of magnetic field effect on nanofluid stability of CuO

Abstract

This study investigates the effect of additional magnetic field on the stability of CuO nanofluid. Experiments are conducted by imposing an additional magnetic field to the CuO nanofluid prepared by the self-developed Arc-Submerged Nanoparticle Synthesis System (ASNSS), so as to investigate the aggregation phenomenon and the stability of the nanoparticle suspension. It is subsequently known that the permeance strength, time and frequency of the additional magnetic field can affect the CuO nanofluid. Under the influence a strong magnetic field, the longer the permeance time, the more apparent the sedimentation phenomenon will be owing to the aggregation of the nanoparticles. However, the permeance frequency has a relatively slight effect on the CuO nanofluid.
