      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.},
