abstract = {Ventricular Assist Devices (VADs) are commonly implanted to
assist patients suffering fromheart diseases. They provide
long- and short-term support for the human heart and help
patientsto recover from heart attacks and from congestive
heart failure. It is essential to design bloodsensitiveVADs
to minimise the risk of hemolysis and thrombosis. The blood
pump, however,must operate at a wide range of flow rates and
pressure heads which makes a low-risk design achallenging
task. In this study the flow in a centrifugal blood pump,
provided by the U.S. Foodand Drug Administration (FDA), is
investigated by means of numerical simulations on
highperformance computers. The simulations are carried out
for different operation REYNOLDSnumbers. A total of 15 pump
revolutions is performed to obtain quasi-steady results. The
pressuredrop across the pump is considered to study
convergence of the solution and to characterisethe energy
loss of the device. Investigations of the velocity field
show that there exist high velocitiesand strong velocity
gradients and shear layers in the outflow region potentially
leadingto hemolysis. Investigations of the wall-shear stress
reveal the existence of thin boundary layersat the blade
tips. Finally, the motor torque is investigated to identify
the force acting onthe blades. All the findings show that
there is a strong need to develop more
blood-sensitivedesigns to reduce the risk of hemolysis and
thrombosis.},
