Cardiovascular diseases including strokes, heart attacks, Stenosis, and atherosclerosis are
considered the leading cause of death over the globe. The aorta, coronary, carotid, and
femoral arteries are the most commonly impacted arteries. It's a crucial field of study for
blood flow behavior. For many years, researchers have experimented with various
numerical strategies to entice clinicians to trust their colorful contours. In recent, the impact
of magnetic fields on blood flow is one of the developing approaches to treating different
types of diseases. However, the efficiency of MHD capture is still unclear, and there is less
systematic strategy to understand the flow behavior of blood. In this study, a simulationbased three-dimensional human aorta (brachiocephalic trunk, left subclavian, and left
carotid) with transient conditions is analyzed to predict changes in blood flow distribution
and flow patterns under with and without magnetic field conditions. Blood is modeled as
non-Newtonian fluids along with plasma. VOF modeling for multiphase flow is used to
mix RBC and plasma to predict the pulsating condition for the flow. Moreover, 1 Tesla
magnetic field is applied to the selected section of the aorta. For simulation purposes,
ANSYS Fluent software is used to identify the values for velocity, pressure, and wall shear
force to understand the flow behavior of blood. The result shows that velocity, pressure,
and wall shear stress are affected by exposure to MHD. By applying MHD, due to the
freezing effect, the flow velocity slows down by about .035% while pressure increases by
9%, wall shear stress increases by 1.46% as well as mass flow. |
