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

In order to clarify the basic characteristics of heterogeneous two-phase flows, systematic experiments are carried out typically hetergeneous sand-water flows through a 7°divergent and a 7°convergent pipe. The recovery pressures in the divergent or

In order to clarify effects of the divergent angle θ upon the hydraulic losses ξm in heterogeneous sand-water two-phase flows through divergent pipes, systematic experiments on ξm and the corresponding flow patterns are carried out for several θ,

Experiments were conducted in the water tunnel by using the model of a Savonius rotor of blades with flaps equiped by deflectors, and the influences of the flaps and the deflectors on the output power-tip speed ratio characteristics and the torque-bl

In order to clarify the Johnsson effects which so often arise in single-foil cavitation-experiments, careful cavitation observations were made around a typical Clark Y foil of 4 percent thickness in our closed type cavitation tunnel, with which a num

To improve the physical understanding of the fatal "violent vibration" in the near-transition range, the "abrupt cavity separations" associated with the vibration were precisely observed in a water flow around two-dimensional hydrofoils, for various

For the first step in this series to clarify the cavitation-nuclei-performance of our cavitation tunnels for a single-foil or cascade-foils, we take up a single-foil tunnel of closed type, with which a number of cavitation-performance-tests had been
