Population

Centrifugal blood pump (CBP) model for left ventricular assist device (LVAD) evaluated via experimental flow loop and computational fluid dynamics (CFD)

Intervention

Varying operational parameters (fluid temperature 16-34°C, rotational speed 2400-3200 rev/min) and geometrical features (surface roughness 0-40 µm, addition of a 3-blade inducer)

Comparator

Baseline pump parameters (e.g., standard temperature, speed, slip surface, no inducer)

Outcome

Pump performance metrics including hydraulic efficiency, pressure difference, power, and wall shear stresssurrogate

Optimizing centrifugal blood pump design with an inducer and smoother surfaces can improve hydraulic efficiency and reduce wall shear stress, potentially lowering hemolysis risk in LVADs.
