A Computational Study of Flow Instabilities in Aneurysms

Abstract The majority of hemorrhagic strokes are caused by cerebral aneurysms, harboured in a large portion the human population. Currently, it is unclear what constitutes dangerous aneurysm, and risk rupture such aneurysms challenging to quantify. Previous studies have shown that flow dynamics play an important role development aneurysms. However, there varying consensus on blood patterns stability. In this work, we formulate Reynolds–Orr method quantify stability arteries. Applying four different arterial models, find therein unstable under physiological conditions. We show most eigenmodes for each these models discuss how they potentially could help explain initiation growth
