Blood flow velocity in stenosed artery

Stenosis is an occlusion of the blood vessels due to the accumulation of cholesterol, fat and the abnormal growth of tissue at the arterial wall. The regional blood rheology is altered once a stenosis develops in the artery. This is due to the presence of stenosis which is one of the factors that cause problem in blood circulation system. This study was conducted to determine the velocity of blood flow in stenosed artery. Modified mathematical model is used to analyze the relationship of the velocity versus the length and height of stenosis. The existing models that have been created by previous researchers are solved using fourth order Runge-Kutta method. Numerical results show that the velocity is proportionate to the length and height of stenosis.
