Some peculiar phenomena occur around ultrahigh-speed submerged water jets accompanied by very severe cavitation erosion. Using the flow visualization technique with a xenon flash, the water jets were carefully observed, and the spatial distributions

In order to establish useful techniques of cutting, drilling, peening and flushing by high-speed submerged water jets, we systematically observe the eroded surface on aluminum-alloy specimens in relation to the characteristics of cavitating jets, esp

The present study explores experimentally the characteristics of flow rates in branch ducts of multiple passages and the flow pattern in the passages by the smoke tracer method, using a reverse-flow-type rectangular multiple-passage-simulated fuel ce

As a first step to finding thin, low-drag foils in cascades applicable to Kaplan turbines of high specific speed, the authors systematically investigate the subcavitation performance and the cavitation aspects, especially those of the leading-edge se

This paper aims to clarify peculiar phenomena arising around a ultra high-speed submerged water jet accompanied by very severe cavitation. By means of a flow visualization technique with a xenon flash light, three kinds of water jets are carefully ob

For the first step to find low-drag thin hydrofoils in cascade applicable to Kaplan-turbines, the subcavitating performance and the corresponding cavitation aspects for two different hydrofoils whose shapes are quite the same except the neighborhood

To clarify cavitation behaviours of submerged high-speed water-jets, systematic experimental studies were carried out by using a flow visualization technique. The cavitation behaviours were studied for both the free jet and the impinging jet at vario
