Simulation of non-Uniform Magnetic Field Impact on nonNewtonian and Pulsatile Blood Flow
Keywords:permanent magnet, COMSOL, magnetic volumetric force, induction magnetization
Blood contains haemoglobin. Haemoglobin is an iron (Fe) containing protein that respond to magnetic field. Regarding imposing blood flow upon magnetic field is not obvious well and or has not been examined completely and extensively and concerning contradictory results that presented by researchers, in this paper, laminar, pulsatile and non-Newtonian blood flow imposed by non-uniform magnetic field were explored with different intensities through using COMSOL 4.4 Finite Element Software. Non-Newtonian Generalized power-law model was applied and with aim of comparison, results were compared with Newtonian mode. Findings indicated that wall shear stress fluctuation amplitude was increased by raising magnetic field intensity for both Newtonian and non-Newtonian modes and reverse flow occurred for 4 and 6 T field’s intensity. Concerning non-Newtonian mode, as the intensity of the magnetic field increases from 0.5 to 1, 1 to 2, 2 to 4, and 4 to 6, the amplitude of shear stress fluctuations will rise to 1.136, 1.729, 3.969, and 1.626 times respectively since non-Newtonian fluid viscos dissipation is higher. Moreover, increased average arterial pressure was achieved in non-Newtonian mode more than Newtonian mode.
