- W408348916 abstract "This paper presents PIV results and CFD results obtained for in vitro flow behaviors in a cerebral aneurysm. Non-pulsating flow, Re=700, is investigated as a first step. The MRI data acquired from an actual patient are reconstructed into a digital three-dimensional model, from which a transparent silicone rubber model suitable for flow visualization is fabricated by using a rapid-prototyping technique. A commercial CFD code based on the finite volume method is utilized. The PIV measurement, realized by the index matching technique, has revealed that the flow velocity in the aneurysm is low, that there is a recirculation zone in the center of the aneurysms and that the flow in the bleb is stagnant. These features are in agreement with the CFD result, which shows in addition that the wall shear stress is high at the entrance and the exit of the aneurysm but low on its internal wall." @default.
