Hydroacoustics in centrifugal pumps
, the centrifugal pump test rig available at HSM (RU Bochum) with a centrifugal pump of nq = 12 min-1 is used as an example. A hydroacoustic methodology 1,2 previously developed at the Chair of Fluidics (TU Dortmund) is extended and adapted for this purpose. The method is based on a 1D characteristic method. In it, the pulsation excitation of a pump is modelled by a monopole and dipole [...] transient pressure measurements, 3D/1D CFD, possibly FEM), the real and idealised excitation can be compared and thus conclusions drawn …
