Computational Modeling of Aortic Stenosis With a Reduced Degree-of-Freedom Fluid-Structure Interaction Valve Model.

Chi Zhu, Jung-Hee Seo, Rajat Mittal,

In this study, a novel reduced degree-of-freedom (rDOF) aortic valve model is employed to investigate the fluid-structure interaction (FSI) and hemodynamics associated with aortic stenosis. The dynamics of the valve leaflets are determined by an ordinary differential equation with two parameters and this rDOF model is shown to reproduce key ... Read more >>

Rayanne Pinto Costa, Blaise Simplice Talla Nwotchouang, Junyao Yao, Dipankar Biswas, David Casey, Ruel McKenzie, David A Steinman, Francis Loth,

Blood, a multiphase fluid comprised of plasma, blood cells, and platelets, is known to exhibit a shear-thinning behavior at low shear rates and near-Newtonian behavior at higher shear rates. However, less is known about the impact of its multiphase nature on the transition to turbulence. In this study, we experimentally ... Read more >>
