Abstract

Particle image velocimetry (PIV) based investigation was carried out to account for the effect of valve rebound on the local fluid flow patterns and thus, by inference, on the local pressures and the cavitational potential. Actual flow rate measurements were used to confirm the average velocity at nozzle exit. The results indicate that the sudden stopping and subsequent rebound motion of the occluder on the higher-speed major orifice side plays a role in the initiation of the vaporous cavitation field there.
