Hemodynamic and fluid flow analysis of a cerebral aneurysm: a CFD simulation

Abstract

Highlights The presence of the aneurysms in the patient's vascular system leads presence of a flow vortex inside the bulge. The flow recirculation occurs due to separation at the rear edge of the aneurysm. The flow-wall interaction due to the flow recirculation produce uneven variation in the wall shear stress (WSS), which help to investigate the region of the rupture. The wall pressure and the wall shear stress have a qualitative similarity in their behavior.
