Abstract

Critical aspects for a CFD simulation compared with PIV analysis of the flow field downstream of a prosthetic heart valve M Grigioni, C Daniele, C Del Gaudio, A Balducci, U Morbiducci, G D'Avenio, V Barbaro Laboratory of Bionzedical Engineering, Istituto Superiore di Sanith, Ronza, Italy Abstract The investigation of the fluid dynamic field determined by the implantation of a medical device is of fundamental importance from a bioengeneering and a clinical point of view: it is well-known that the modification of the physiological fluidic condition could generate thrombogenic andlor hemolytic phenomena. Several techniques can be implemented for this study (PIV, PTV, CFD), but none of them can be regarded as completely exhaustive; intrinsic technical limitations can lead to approximate results. This paper presents a numerical analysis of the flow field downstream of a prosthetic bileaflet heart valve in aortic position, placed in a glass test chamber designed as the natural aortic root for in vi
