Transient Simulation of Blood Flow in Brain Artery

Cardiovascular disease has become one of the serious killers in the world. The risk
factors for the disease could be hypertension, high cholesterol content, and high glucose
level in the body. One of the important risks that are being study is the high blood
pressure or hypertension risk. This risk may lead to the stroke to occur. The stroke
normally occurs in the middle cerebral arteries in the brain. The effect of the heart
pulsatility on the person is being investigated throughout the project. As the pulsatility
of every person is varies according to their health condition, it may lead to the onset of
the cardiovascular disease. The study is categorized to three groups, which are the
healthy person group, the hypertension group and the high cholesterol group. The
different behavior of the blood flow of every group is carried by using FLUENT, Ansys
software. The project also will determine the relationship of the pulsatility to the wall
shear stress. From the simulation conducted, the hypertension and high cholesterol
patient may have the potential to get stroke, as the wall shear stress measure is exceed
the normal pressure of 1Pa.
