Modal Decomposition Techniques: Application in Coherent Structures for a Saccular Aneurysm Model

Aneurysms are localized expansions of blood vessels which can be fatal upon rupture. Studies have shown that aneurysm flows exhibit complex flow phenomena which consist of single or multiple vortical structures that move within the flow cycle. ...Rep and α were the inflow parameters used to match and simulate the conditions in the human circulatory system. These inflow parameters were precisely controlled with a ViVitro Labs Inc. SuperPump system... ...Both POD and DMD are capable analysis tools to investigate the spatial and temporal behavior of large-scale structures of a given flow field. POD and DMD can be used to create mathematical models to look into the flow evolution in sufficiently high detail and at any time step...
