Abstract: This study presents numerical simulations of a minimally constrained mechanical valve model using a fully coupled fluid-structure interaction method with COMSOL Multiphysics, a finite-element-based software package. The model applies a physiological pulsatile pressure gradient across an aortic valve with an approximately symmetric aortic root. The complex hinge from the exact model is simplified with a pin joint and weak constraints to control the designated valve leaflet positions. The arbitrary Lagrangian-Eu… Show more

“…Having applied ALE to 2-D geometry of BMHV, Dumont et al [7] obtained velocity profiles for systolic phase of cardiac cycle and validated the results experimentally. Nobili et al [8] and Yeh et al [9] developed a 3-D model of the valve, and employed ALE to study hemolytic properties of blood flow during different phases of cardiac cycle. Their results were found in good agreement with experimental measures.…”
