      abstract     = {While for the design point operation of centrifugal pumps,
                      where an essentially steady flow field is present and
                      statistical turbulence models yield an appropriate
                      prediction of the characteristics, the flow field gets
                      increasingly unsteady towards off-design operation. Special
                      designs as e. g. sewage pumps are characterised by a
                      single-blade impeller and show significantly unsteady
                      characteristics even in the design point. For such
                      highly-unsteady and turbulent flow fields, statistical
                      models tend to fail. On the other hand, Large-Eddy
                      Simulation models, where the large-vortex part of the
                      turbulent spectrum is directly resolved, show a much better
                      flow prediction. However, the spatial resolution and thus
                      computational effort are too high for engineering real pump
                      applications. Therefore, we provide an assessment of
                      scale-adaptive turbulence simulation (SAS) models that
                      recover a statistical flow solution in regions of low
                      unsteadiness and – like Large-Eddy Simulation – resolve
                      a part of the turbulent spectrum down to the available grid
                      resolution for highly unsteady flow regions. After a
                      thorough validation on standard turbulence test cases e. g.
                      the periodic hill case, it is shown that with a moderately
                      higher computational effort than statistical models, the SAS
                      yields a considerable improvement of the prediction of the
                      turbulence field in part load operation of a centrifugal
                      pump while the mean flow field could be well predicted even
                      with a well-established statistical model.},
