RISPulsatile Flow Visualization in the Abdominal Aorta Under Differing Physiologic Conditions: Implications for Increased Susceptibility to Atherosclerosis
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: The infrarenal abdominal aorta is a common site for clinically significant atherosclerosis. As has been shown in other susceptible locations, vessel geometry, flow division rates, and pulsatility ...
Mechanical Analysis of Heterogeneous, Atherosclerotic Human Aorta
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: An experimental technique was developed to determine the finite strain field in heterogeneous, diseased human aortic cross sections at physiologic pressures in vitro. Also, the distributions within ...

Shear Stress at a Compliant Model of the Human Carotid Bifurcation
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: To investigate the role of a compliant wall to the near wall hemodynamic flowfield, two models of the carotid bifurcation were constructed. Both were of identical internal geometries, however, ...
An Automated Three-Dimensional Particle Tracking Technique for the Study of Modeled Arterial Flow Fields
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: An automated three-dimensional particle tracking technique has been developed to study particle motion in modeled flow fields. A high speed video recording system, Kodak Ektapro 1000, with two ...
Measurements of Velocity and Wall Shear Stress Inside a PTFE Vascular Graft Model Under Steady Flow Conditions
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: The flow field inside a model of a polytetrafluoroethylene (PTFE) canine artery end-to-side bypass graft was studied under steady flow conditions using laser-Doppler anemometry. The anatomically ...
Hemodynamic Patterns in Two Models of End-to-Side Vascular Graft Anastomoses: Effects of Pulsatility, Flow Division, Reynolds Number, and Hood Length
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Flow behavior in models of end-to-side vascular graft anastomoses was studied under steady and pulsatile flow conditions. Models were constructed to simulate geometries employed in experimental ...
