Impact of iron oxide particles concentration under a highly oscillating magnetic field on ferrofluid flow

摘要

In the present study, an oscillating magnetic force into the fundamental hydrodynamic equations is introduced. In modeling, nanoparticles rotation and clustering effects that are produced by the high oscillating magnetic field on viscosity and thermal conductivity are taken into account. This study precisely examines the impacts of a high oscillating magnetic field and nanoparticle concentration on physical properties as well as on mass and heat transfer and their results are discussed through graphs, tables and bar charts. The results expose that a highly oscillating magnetic field produces a rotational effect on viscosity which reduces the total viscosity and creates a percolating nanoparticles path which enhances thermal conductivity. Thus, these effected physical properties play a role to improve the fluid flow and heat transfer rate.
