Diseased or damaged heart valves can interfere with blood flow and adversely affect the performance of the heart. Artificial heart valves are implantable devices that keep blood flowing properly. Computational fluid dynamics (CFD) simulations are a low-cost, low-risk approach to evaluate the performance of an artificial heart valve before performing an invasive procedure. In this webinar, we demonstrate how CONVERGE CFD software can be applied to model a 3D mechanical leaflet heart valve. CONVERGE’s autonomous meshing makes it simple to set up simulations with fluid-driven valve motion. Because the density of blood is similar to the density of the leaflets, the added mass effect is significant and can cause explicit fluid-structure interaction (FSI) solvers to become unstable. CONVERGE’s implicit FSI solver can account for the additional inertial forces from the added mass effect and accurately predict the leaflet motion profile. The relatively fast turnaround time and the stability of the numerical analysis highlight the potential of CONVERGE for a wide range of biomedical fluid dynamics problems.
