Abstract
In the present study, we
report on the results of an experimental study of pressure pulsations in the
flow duct of a medium-scale hydrodynamic bench with Francis turbine. In various
regimes, integral and pulsation characteristics of the turbine were measured.
With the help of high-speed filming, the structure of the flow behind the
turbine runner was analyzed, and the influence of this structure on the
intensity and frequency of pressure pulsations in the flow duct was
demonstrated.
