A novel particle tracking velocimetry (PTV) algorithm based on Voronoi diagram (VD) is proposed and briefed as VD–PTV. The robustness of VD–PTV for pulsatile flow is verified through a test that includes a widely used artificial flow and a classic reference algorithm. The proposed algorithm is then applied to visualize the flow in an artificial abdominal aortic aneurysm included in a pulsatile circulation system that simulates the aortic blood flow in human body. Results show that, large particles tend to gather at the upstream boundary because of the backflow eddies that follow the pulsation. This qualitative description, together with VD–PTV, has laid a foundation for future works that demand high-level quantification.
