Simulation and visualization of transient SD-flow in arteries with an artificial heart valve using Lattice-Boltzmann methods

Author(s): M. Krafczyk, M. Schulz, E. Rank & M. Cerrolaza Abstract: The development of flow instabilities due to high Reynolds number flow in artificial heart valve geometries inducing high strain rates and stresses often lead to hemolisis and related highly undesired effects. Geometric and functional optimization of artificial heart valves is therefore mandatory. In addition to experimental work in this field it is meanwhile possible to obtain increasing insight into flow dynamics by computer simulation of refined model problems. We report the results of the simulation of three dimensional fully transient physiological flows in a geometry similar to a Ca... Pages: 10 Size: 1,924 kb Paper DOI: 10.2495/BSIM960081
