Numerical Simulation of Blood Flow Mixed with Magnetic Nanoparticles under the Influence of AC and DC Magnetic Field

Abstract

Nanoparticles combined with magnetic fields are one of the most important research areas in the field of biomedical engineering. Direct Current (DC) magnetic and Alternative Current (AC) magnetic fields are often used for controlling nanoparticles. It is also used for hyperthermia treatment. The purpose of the current study is to investigate the effect of DC and AC magnetic field on nanoparticles mixed with biofluid (non-Newtonian blood).The coupled nonlinear equations continuity, momentum, concentration and energy are solved with finite volume code. Results show that increase in blood temperature doesn't influence the nanoparticles concentration as well as the velocities and pressure distribution of bloodinside the channel. In addition results show that the DC magnetic field absorbs magnetic nanoparticles and the AC magnetic field induces energy into nanoparticles. Also the eddy current, as the only source of energy in this study, doesn't change the blood flow temperature. Finally it is shown that magnetic nanoparticles mixed with magnetic fields are a good tool for medical applications.
