Abstract:Fluid–structure interaction (FSI) problems in modeling flexible structures and moving boundaries can be simulated by combining the immersed boundary (IB) method and the Lattice–Boltzmann (LB) method. In this paper, we propose an FSI model of mitral valve leaflets and the left ventricle to simulate the flow field in the left ventricle during diastolic filling based on an IB–LB coupling scheme. Changes in the flow field and mitral valve leaflets in the FSI model are simulated with the IB–LB method, in which two … Show more
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
