    Design of Centrifugal Blood Pump
    (01. Izmir Institute of Technology, 2020) Sarızeybek, Ceren; Özkol, Ünver
    In this thesis a maglev centrifugal blood pump is studied numerically which will be used in ECMO systems. Aim was to design a pump with 3.3 L/min at 5000 rpm having 200 mmHg head. Pump is designed by SolidWork and CFD studies are applied in Ansys Fluent. Firstly, blade discharge angle values between 20 degree and 40 degree are simulated with 5 degree intervals and 35 degree is found to be the most appropriate for hydraulic efficiency and head. Likewise, six different up-clearance values between 2.0 mm and 0.1 mm are studied to see effect of up-clearance on head and efficiency. Also to predict hemolysis for different up-clearance values, Giersiepen power law hemolysis model with Lagrangian approach is employed. 0.1 mm up-clearance is found suitable. For this up-clearance hemolysis is calculated as 4%.
