Abstract: Particle image velocimetry was used to measure the flow structures in evolving scour holes caused by a plunging jet downstream of a weir. The results clearly depict that four different types of roller were involved in scour ...

Abstract: This paper presents an experimental investigation of the flow fields in a centrifugal pump by particle image velocimetry (PIV) technique with two different tracer particles, all designed for the same operating point. In ...
