RISEffects of Wall Motion and Compliance on Flow Patterns in the Ascending Aorta
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Helical flows have been observed in the ascending aorta in vivo, and geometric curvature has been suggested to be a major contributing factor. We employed magnetic resonance imaging (MRI) and ...
Computation of Turbulent Flow through Constrictions
Publisher: American Society of Civil Engineers
Abstract: The turbulent flow through an axisymmetric constriction in a tube is studied using the
Choice of In Vivo Versus Idealized Velocity Boundary Conditions Influences Physiologically Relevant Flow Patterns in a Subject-Specific Simulation of Flow in the Human Carotid Bifurcation
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Accurate fluid mechanics models are important tools for predicting the flow field in the carotid artery bifurcation and for understanding the relationship between hemodynamics and the initiation ...
Relative Contribution of Wall Shear Stress and Injury in Experimental Intimal Thickening at PTFE End-to-Side Arterial Anastomoses
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Background : Intimal hyperplastic thickening (IHT) is a frequent cause of prosthetic bypass graft failure. Induction and progression of IHT is thought to involve a number of mechanisms related ...
