..., using particle image velocimetry (PIV) to get the accurate flow velocity, and the drag coefficients of nets with different side lengths and solidities normal to the free stream were obtained. It was found that the drag coefficients of the nets were negatively related to the side length, which also...

... ABSTRACT In this study, steel net panels with different twine diameters, mesh sized were tested in the current-wave flume. The hydrodynamic forces of the steel net panels were measured in current and regular wave, respectively. The effect of the net solidity, the Reynolds number...

... the net cage. The effect of net solidity on the flow pattern around the net cage is investigated by numerical simulation. The results indicate that the same net solidity may produce different vortex pattern around the net cage. A vortex first appears near to the net mesh and then a large-scale vortex...

As a result, the design materials for the solidity of the axial flow runners suitable for the given water circumstances are induced...

... investigations have been performed for two solidities by model testing and numerical simulation. As a result, it has been concluded that a suitable choice, namely the preferable rotor geometry, is the blade profile of NACA0015. Furthermore, it has been found that the critical Reynolds number of the turbine seems...

... In order to improve the performance of a Wells turbine, effects of the gap between rotor and guide vane and solidity of the guide vane have been investigated by model testing. The results have been compared with those of the case without guide vane. It is found that the overall characteristics...
