Two-dimensional design and analysis of centrifugal blood pump impeller

The objective for impeller's blade curvature design is to achieve high efficiency and head generation for the pump, while at the same time minimising the highly sheared turbulent flow within the pump. The blades' curvatures are assumed to have constant thickness and were modelled numerical...
