Patient-Specific Aorta Flow Analysis with the Space-Time VMS Method and Isogeometric Discretization

Abstract

The Reynolds and Womersley numbers of the flow in human aorta are higher than those in the other arteries. This makes the flow more complex in the aorta, and accurate computational analysis more challenging. To address the computational challenges, we use a method consisting of two main components: Space-Time Variational Multiscale (ST-VMS) method and Isogeometric Discretization in the ST context (ST-IGA). The main objective in this research is to obtain reliable wall shear stress distribution with ST refinement study. We also assess the unsteady flow patterns in the aorta.
