Experimental study of flow structure impact on the fluid parameters in saccular aneurysm models

Aneurysms are abnormal expansion of weakened blood vessels which can be debilitating or fatal upon rupture. Previous studies have shown that hemodynamics play a role in aneurysm formation, growth and rupture. Therefore, the objective of this work is to investigate the impact of flow structures on vortex strength, impinging location, and wall shear stress for two aneurysm models. ...The inflow parameters used in this study, and , were controlled using a ViVitro Labs Inc. SuperPump system... ...The flow evolution results showed that impacted the vortex formation, growth, and dissipation processes for the studied aneurysm model...
