Shear Stress and Shear-Induced Particle Residence in Stenosed Blood Vessels
SINOPSIS
Numerical analysis of pulsatile blood flow in stenosed carotid arteries is performed to define hemodynamic factors in the initiation, growth, and potential of leading to severe occlusions of a diseased artery. A fluid-structure interaction algorithm, the immersed finite element method, is used for this study for its convenience in imposing arbitrary stenotic shapes without remeshing. Our computational results provide detailed quantitative analysis on the wall shear stress, shear-induced particle residence time, and oscillatory shear index. The analysis of these parameters leads to a better understanding of blood clot formation and its localization in a stenosed carotid artery. A healthy artery is also studied to establish a baseline comparison.
