Clarification of Internal Flow Characteristics of an Axial Flow Blood Pump with Eccentric Drive

Abstract

In this study, The reduction rate of rotation speed was investigated by a hydraulic test. As a result, it was found that the eccentric shaft could reduce the rotational speed from 8.2% to 9% and The loss factor was found to be reduced by 33%.Also the internal flows were clarified by PIV .The driving condition in the PIV was 2.0 L / min at 10000 rpm, and axial velocity distribution was measured and compared.
