Abstract

To clarify the capacity effect by cavitation bubbles, the cavitation aspects and the vibrational acceleration were studied experimentally in pulsating flows through a branch duct. When the pulsation is given on the upstream side, the wall pressure and the flow velocity fluctuate in phase, while when the pulsation is given on the downstream side, there is a phase difference of 90° between them. The incipient and the desinent cavitation number have approximately the same value. The characteristics of such pulsations are independent of the pulsating conditions and the types of cavitation.
