Background and aim of the study: The study aim was to characterize time-dependent flow fields and flow structures within the ADVANTAGE (ADV) and St. Jude Medical (SJM) prosthetic bileaflet mechanical heart valves.
Methods: Three-dimensional unsteady computational fluid dynamic simulations were conducted in the aortic position for both valves. Flow boundary conditions were acquired from an in-vitro experiment. The governing equations were solved by a finite volume method that employed a moving cell technique to simulate the motion of the valve leaflet in the cardiac cycle. The computed velocities were subsequently validated using the velocities measured in the in-vitro experiment.
Results: Both valves had similar flow phenomena at the geometric symmetry plane of the valve housing, and both experienced a waterhammer effect upon closure. However, flow characteristics in the pivots diff...
