| Popis: | In complex vessel geometry different temporal, spatial variation takes place which occur under pulsatile conditions. The high Wall Shear Stress (WSS) at the wall affected by the disturbed flow may ultimately lead to endothelial cell dysfunction, which leads to atherogenesis and thrombosis. The present study observes WSS and streamlines due to stenosis with and without By-pass Artery. It was found that by adding bypass Artery there is tremendous decrease in wall shear stress in the stenosis. Reverse flow of blood through stenosis was observed in 30° Bypass Models. Hence the blood flow stabilizes and can be reached at optimum level in 50% stenosed artery. Based on this paper findings, it can be deduced that there would be a low risk of further atherosclerosis when the bypass artery is added. |
