Revealing the details of blood flow through mechanical heart valves with CFD simulation

Learn how simulation and design exploration tools from Siemens PLM Software can help you meet the challenges of accelerated design cycles and risk management in medical device development, as part of a broader strategy of Digital Evidence Generation.

Designing the next generation of mechanical heart valves requires a detailed understanding of the fluid and structural interactions that occur as the blood flows through them. To enable this, design engineers in the medical device industry require a number of key technologies to be readily available in their daily simulation work. Among them:

• STL geometry preparation
• Computational Fluid Dynamics (CFD) with overset meshing and mesh morphing
• Dynamic Fluid-Body Interaction (DFBI)
• Finite Element Analysis (FEA), and
• Fluid-Structure Interaction (FSI)

You can find them all within Simcenter, the Siemens PLM simulation environment. 

CFD/FEA analyst Fardin Khalili, PhD, present and discuss his findings on CFD and sound analysis of a bileaflet mechanical heart valve, highlighting the use of overset meshing and DFBI, with a focus on turbulence effects.

Simcenter STAR-CCM+ Product Manager Rafael Ritterbusch provide an overview of the latest FEA and FSI capabilities as they pertain to applications in the Medical Device industry.

The presenters highlight tools that are available to help improve not only your design process, but also augment your benchtop, in-vitro and in-vivo tests through simulation.
