摘要：

In computational fluid dynamics (CFD) of circulatory system, fluid-structure interaction simulation, for example blood flow and vascular wall, is necessary. Particularly, a fully Eulerian solution, which can evaluate deformation of an object on fixed spatial grid, is required by reason of high-affinity for medical images obtained by medical diagnostic imaging apparatus, for example MRI and CT. The goal of present study is to establish a fully Eulerian solution for blood flow simulation around the aortic valve which is assumed that it is thin film elastic body. Thus in this work, we reproduced opening and closing motion of aortic valve in response to relationships between left ventricular and aortic pressures. Additionally, we observed vortex evolved from the tip of the valve in the sinus of Valsalva. © 2014, Japan Soc. of Med. Electronics and Biol. Engineering. All rights reserved.
