Abstract: The main goal of the present research was to determine the value of the mechanical parameters with which a material to be used in a blood pump impeller must comply. To obtain these values, multiphysical numerical simulation and modeling of the Fluid-Structure Interaction (FSI) of the impeller with defined conditions and geometry was carried out, by means of Computational Fluid Dynamics (CFD) based on the Finite Element Method (FEM), specifically the partitioned procedure was used. As a result of the simulations, the deformed geometries, the maximum values of the Von Mises stress and the volumetric deformations for an axial impeller with a central shaft were obtained. From this research it was determined that from the structural point of view the selected biocompatible polymers are candidates for the manufacture of the impeller.
