Abstract: This paper describes the development of a passive system to control the output power of a horizontal axis wind turbine. This pitch-flap coupling mechanism can reduce rotor power above rated ...

Abstract: This paper presents a discussion of the physics of the flow discussed in our first report (Shimizu, Y. et al., 1990). By visualizing the flow around the tip vane, the following results were ...

Abstract: This paper describes the experimental results of output power augmentation of a horizontal axis wind turbine with a tip vane. In order to find the relationship between the performance of the ...

Abstract: This paper describes the relationship between hydraulic losses and secondary flow within sinuous conduits with complicated bends. It has been found that the nature of secondary flow present in ...

Abstract: In this paper, we investigated experimentally the relation between configuration and performance of the annular type jet pump and compared it with that of the central jet type. Twenty-five ...

Abstract: This paper is the result of our research into the twisted S -shaped bend diffuser—the so-called coiled bend diffuser. It is a diffuser with a centerline in the shape of a twisted “S .” Our ...

Abstract: This paper describes the relation between bend diffuser characteristics and internal flow. Diffusers were bent into U and snake shapes within the limitation of a single plane. In these experiments, ...
