Clearly, This Heart Beats Strong
Rice University's Tayfun Tezduyar said the simulation incorporates the valve mechanism and fluid flow through the aorta and its three branch arteries.

Researchers at Rice University and Japan's Waseda University have developed a model that simulates the flow of blood through the heart.
The model of a working ventricle-valve-aorta provides a detailed view of how the ventricle fills with blood, how quickly the three-leaf valve opens to relieve the pressure, and the flow of blood as it pushes through.
Said Rice's Tayfun Tezduyar, "This is a computational technology that no one else in the world currently has with this level of accuracy near the leaflet surfaces."
Tezduyar explained, "Modeling three-leaflet valves that touch each other, fully close off blood flow and then open again, and doing that with accurate representation of the near-leaflet flow patterns, is a new and challenging class of problems in fluid mechanics."
Tezduyar said the research could help doctors evaluate replacement valves for patients with heart disease.
