Theoretical and Practical Investigation of Blood Flow through Stenosed Coronary Lad Artery

Atherosclerosis is the most common causes of vascular diseases and it is associated with a restriction in the lumen of blood vessels. So; the study of blood flow in arteries is very important to understand the relation between hemodynamic characteristics of blood flow and the occurrence of atherosc...
