摘要

Abstract The present work presents a numerical study of two axial ventricular assist devices (VADs) with two different designs. The geometry of the first design was inspired by DeBakey's rotary blood pump and the geometry of the second design is based on BioCirc’s pediatric VAD. The goal is to see which of the two designs has promising capabilities in terms of pressure differential, flow rate, and thrombosis before proceeding to deeper investigations. In this study a computational fluid dynamics tool was used to simulate and calculate the hemodynamics in the two investigated models. Both models were investigated for a flow rate of 5 L/min at rotational speeds between 10?000 and 15?000 rpm.
