Abstract

The steady and transient flow simulations in an aorta model of normal subject were carried through computational fluid dynamic (CFD) technique. The steady- and transient-state computational fluid dynamic models of patient-specific aortic aneurysm were developed. The computed tomographic (CT) image data was used to generate the geometry of aortic models. The laminar flow was considered for simulating the flow of blood. The haemodynamic parameters like wall pressure, wall shear stress (WSS) and velocity distribution were estimated from the models. The obtained results depicted that the flow in the aorta model of normal subject was stable and aneurysmal aorta model became unstable. It is observed from the steady-state analysis that all the measured parameters from aneurysmal aorta model were higher than those obtained from the aorta model of normal subject. These measured parameters from this study could help the surgeons in assessing the severity of aortic aneurysms.
