The Computational Fluid Dynamics of Blood Flow in the Heart and Great Vessels

9509829 Cheer本项目的研究目的是为详细了解主动脉瓣周围区域及下游升降主动脉带瓣动壁脉动流的三维流体物理提供基础。辅助目标是：(1)生成切应力的详细图，并分析其对心脏和大血管中悬浮颗粒的影响；(2)对向心肌供血的冠状动脉开口处的血流模式进行详细建模。＊＊＊

9509829 Cheer This project is on research to provide a foundation for the detailed understanding of the three-dimensional fluid physics of pulsatile flows with valves and moving walls in the region around the aortic valve and the downstream ascending and descending aorta. Subsidiary objectives are: (1) to produce a detailed map of shear stresses and analyze their effect on suspended particles in the hart and large vessels, and (2) to do detailed modeling of the flow pattern at the ostia (opening) of the coronary arteries which supply blood to the heart muscle. ***
