- The flow characteristics in a vaneless diffuser with a backswept radial impeller have been experimentally investigated
according to the variation of discharge flow rate. Particle image velocimetry(PIV) system was applied to measure velocity fields
with several operating conditions and on some diffuser horizontal planes. Pressure transducers were installed on hub wall of
the diffuser in order to analyze the pressure fluctuations and their corresponding velocity fields. The results show that the
location of the main flow center moves from the hub to the shroud side as the flow rate decreases, and the reverse flow is
locally generated on the hub side.
