Simulation and analysis of flow in different geometrical arrays of a vascular graft

Blood flow dynamics has a fundamental role in the success of vascular grafts. In particular, shear stresses and secondary flows are involved in platelet activation and aggregation. In order to investigate these three dimensional flow characteristics, a program was developed and applied to the result...
