Recently, wind energy is observed as the energy which the environmental load is little. Especially, smll-size wind turbine being used in urban district as a emergency electric power source, increases. However, the wing tip noise which accompanies with the high turning speed of the turbine is the problem which cannot be ignored. Then, in this dissertation for noise measurement, the low-noise wind tunnel is produced. And using this apparatus, occurrence circumstance of wing tip noise is considered on the basis of the flow visualization result. Finally, the attempt which decreases blade tip noise by using the tripping wire is described.

An Experimental'Study of a Suitable Combination of a Flanged Diffuser and Wind Turbine for Higher Performance

Recently, Ohya et al.have developed an effective wind-acceleration system.Although it adopts a diffuser-shaped structure surrounding a wind turbine like the others previously proposed, the feature that distinguishes it from the others is a large flange attached at the exit of diffuser shroud.A flange generates a large separation behind it, where a low-pressure region appears to draw more wind compared to a diffuser with no flange.Owing to this effect, the flow coming into the diffuser can be effectively concentrated and accelerated.To develop a shrouded wind turbine for higher performance, we tried to find a suitable combination of a flanged diffuser and wind turbine.We made some diffusers and wind blades by using a simple theory for the wind turbine with a flanged diffuser and measured the output power of shrouded wind turbines in a wind tunnel experiment.
