Abstract :

In this paper, numerical simulation of Coronary Artery Bypass Grafting with complete bypass graft and end to side bypass graft are presented. The numerical model is validated with published model in the Design Modeler and developed for 70 % occlusion and 30o anastomosis angle. The numerical performance for a k-Ω turbulence model with SST is used to analyze wall shear stress. The wall shear stress plays a pivoting role for the development of stenosis in the artery. The wall shear stress is calculated in the key areas of the flow domain such as area near the stenosis and the toe region of anastomosis. The comparative studies for both bypass grafting methods shows that at the critical regions wall shear stress with End to Side bypass grafting has higher value compared with the complete bypass grafting. This presented study may be helpful to understand the real mechanism of Intimal Hyperplasia.
