The rotary blood pumps with a magnetically suspended impeller has shown its superiority as compared to other blood pumps. However, there is still insufficient understanding of fluid dynamics related issues in the clearance gap of a BVAD. Hence, our research focus is in the prediction of blood trauma in the clearance gap of a BVAD. Computational Fluid Dynamics (CFD) is useful for estimating blood damage through the disk clearance of a magnetically suspended centrifugal blood pump for design of a BV AD centrifugal heart pump. In this study, CFD analysis was performed to quantify scalar shear stress through the leakage path and investigated the effects of axial clearance and rotational speed on scalar shear stress to evaluate prototype pump design.
