Mike’s paper, Fluid-structure interaction models of bioprosthetic heart valves: Initial in vitro experimental validation, is now available on the engrXiv. This paper uses the hyperelastic immersed boundary method to simulate the dynamics of bioprosthetic heart valves (BHVs) in models 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.
Jianhua’s paper with Amin, An immersed interface-lattice Boltzmann method for fluid-structure interaction, has been accepted to appear in Journal of Computational Physics. (A preprint is available on the arXiv.) This paper develops what is, so far as we know, the first extension of the immersed interface method to lattice Boltzmann method-based descriptions of fluid flows.
