A NUMERICAL STUDY OF THE BLOOD FLOW BEHAVIOR IN CORONARY ARTERY ANOMALIES FOR NORMAL AND DIABETIC PERSONS

This work is developed to facilitate studying the flow of blood through a stenosed coronary artery of a diabetic person. It is Important in the diagnosis, risk assessment, and management of patients with known or suspected coronary artery disease where the major cause of death worldwide is the cardiovascular diseases. Two different cases of coronary artery were investigated to demonstrate the difference between blood flow in a normal and stenosed artery for both normal and diabetic persons. A 3D model was designed and meshed using ANSYS Program, the outputs of the computational fluid dynamics analysis were observed. This paper shows full and non-invasive visualization of the blood flow with high degree of precision that can be applied to the heart diseases. The results show that the disturbed flow patterns and oscillating velocity indicate that the vulnerability of plaque formation is high in case of diabetes. The increasing in blood viscosity causes a deviation in the wall shear stress especially in the presence of stenosis.
