Mike’s paper, Fluid-Structure Interaction Models of Bioprosthetic Heart Valve Dynamics in an Experimental Pulse Duplicator, has been accepted to appear in Annals of Biomedical Engineering. (A preprint is available on engrXiv.) This paper uses IBAMR’s version of the immersed finite element method to simulate the dynamics of bioprosthetic heart valves (BHVs) in the aortic test section of experimental pulse duplicator systems. An initial experimental validation of the models is demonstrated through comparisons to data on pressures, flow rates, and leaflet kinematics. The paper also contrasts the flow patterns and leaflet strains and stresses generated by porcine tissue and bovine pericardial BHVs, and demonstrates the ability of the model to capture the large scale flow features.
