... on the instantaneous and phase-averaged inner structures of the tip flow and evolution of the TLV. Observations are based on series of high resolution planar particle image velocimetry measurements performed in a transparent waterjet pump fitted into an optical refractive index-matched test facility. Velocity...

...Jianjun Feng; Friedrich-Karl Benra; Hans Josef Dohmen The periodically unsteady flow fields in a low specific speed radial diffuser pump have been investigated both numerically and experimentally for the design condition ( Q des ) and also one part-load condition ( 0.5 Q des ) . Three-dimensional...

...Paolo Boncinelli; Roberto Biagi; Antonio Focacci; Umberto Corradini; Andrea Arnone; Marco Bernacca; Massimiliano Borghetti In this paper, the aerodynamic design of a bowl-type diffuser for a low specific-speed pump is presented and described in detail. The main goal was to achieve an optimal...

...Yasushi Tatebayashi; Kazuhiro Tanaka; Toshio Kobayashi The authors have been investigating the various characteristics of screw-type centrifugal pumps, such as pressure fluctuations in impellers, flow patterns in volute casings, and pump performance in air-water two-phase flow conditions. During...
