1. FSI modeling and simulation of blood viscosity impacts on cavitation in mechanical heart valves

Author

Amponsah, Joseph, Archibong-Eso, Archibong, Aliyu, Aliyu M., and Awotwe, Tabbi Wilberforce

Abstract

•Detailed FSI model of tMHVs incorporating non-Newtonian blood behaviour.•Simulation reveals sharp pressure drops as primary drivers of cavitation.•High-speed leakage flows and shear stress regions critical in cavitation dynamics.•Vapor bubble formation and shock waves damage tMHV surfaces and tissues.•Study recommends improved design and validation routes for artificial heart valves.
