Pulsatile flow of thixotropic blood in artery under external body acceleration and uniform magnetic field: Biomedical Application

In this work, a numerical model is carried out to investigate the magneto-hemodynamics of blood driven by an oscillating pressure gradient and exposed to a uniform magnetic field and an external body acceleration. The non-Newtonian nature of blood was taken into account using a time-dependent thixotropic model. Incompressible, axisymmetric, and laminar flow assumptions were used to simplify the non-linear partial differential equations. The velocity field and wall shear stress distribution are numerically solved using the finite difference method. The analytical solution of the velocity distribution of a fully developed pulsatile flow of a Newtonian fluid is used to validate the numerical solution. Further research is done into how structural traits, the average of the pressure gradient, body acceleration, and the magnetic field affect the magneto-hemodynamic properties of blood. The findings indicate how the various characteristics taken into account affected the blood's magneto-hemodynamic behavior in arteries.
