摘要: In medical practice, bypass grafts are commonly used as an alternative route around strongly stenosed or occluded arteries. contrast to arterial bifurcations, surgically created anastomosis can be modified with the objective of enabling optimal graft geometry yield a flow environment that improves its longevity. This paper presents three dimensional numerical study blood through systems different geometries. Coupled finite element solver shape optimization framework considering genetic algorithm is presented. Numerical results show benefits understanding hemodynamic at junctions achieving design improvements. Minimizing recirculation zones and stagnation useful in surgical planning.
