Abstract: Wall shear stress is one of the major factors responsible for increase in cardiovascular disease. The present work calculate the level of wall shear stress in the common carotid artery (CCA) and aorta to see which artery has more chance of having cardiovascular diseases and at which age. Wall shear stress (WSS) is determined in the CCA and aorta of presumed healthy volunteers, having age between 10 and 60 years. A real 2D model of both aorta and common carotid artery is constructed for different age groups using computational fluid dynamics (CFD). WSS of both the arteries is calculated and compared for different age groups. It is found that with increase in diameter of common carotid artery and ascending aorta with advancing age wall shear stress decreases. WSS of aorta is found less than common carotid artery.
