Abstract	This study evaluated the performance of a centrifugal blood pump designed for the children with heart failure. In this work, to better understand the hemodynamic effects of LVAD outflow-graft anastomosis location, a 3D blood pump model is constructed and patient-specific of ventricular volume is considered. The aim of the research is to observe the impact of the physiological waveform, the periodic ventricular volume signal as import boundary conditions. The distribution of pressure, streamlines and wall shear stress of the blades were calculated under all of the continuous period. The hemolysis of the pump was predicted. The result of computational fluid dynamics under unsteady state shows that the Centrifugal Blood Pump for the Children with Cardiac Failure is running stability under a Physiological waveform import, and pressure of the outlet of the pump is fit the periodic demand.
