Aneurysms are localized expansions of weakened blood vessels that can be debilitating or fatal upon rupture... ...the objective of this study was to demonstrate the application of Proper Orthogonal Decomposition (POD) to study the impact of different inflow conditions on energetic flow structures and their temporal behavior in an aneurysm. To achieve this objective, experiments were performed on an idealized rigid sidewall aneurysm model. A piston pump system was used for precise inflow control, i.e., peak Reynolds number ($Re_p$) and Womersley number ($\alpha$) were varied from 50-270 and 2-5, respectively.... … These settings provided approximately 9000 vectors in the pipe region, 6000 vectors in the neck region, and 6800 vectors in the sac region. 3.3 Pump system To generate controlled inflow conditions for this study, a piston pump (ViVitro Labs Inc …Go to the Article
