Abstract

Blood flow dynamics play an important role in the initiated and developed cerebral aneurysm. In particular, the wall shear stress (WSS) acting on an aneurysm surface is believed to be responsible for the cytological effect leading to the long-term growth of the aneurysm. The present paper describes in vitro measurement of WSS inside an aneurysm model that is generated from MRI and rapid prototyping. The WSS is evaluated from an in-plane distribution of three-component mean velocities measured with the stereoscopic PIV. A WSS evaluation technique applicable to complex three-dimensional geometry like aneurysm is proposed here and its accuracy and validity is discussed.
