A Coupled Fluid-Structure Analysis of Dicrotic Pulsatile Blood Flow through an Artery Using Finite Element Method

Abstract

To confirm the formation of dicrotic pulse waveform of blood flow due to the elastic effect of artery, a fully coupled fluid-structure interaction finite element analysis were performed. Artery, blood, and blood ejection effect were modeled with a straight elastic tube, Navier-Stokes fluid model, and intermitted volumetric pulse wave. Significant dicrotic waves were observed for the elastic modulus 0.3 MPa and the level of dicrotic wave decreased for the elastic modulus 3.0 MPa.
