Natural energies such as solar energy and wind power, have been attracted the attention in the world. The micro hydraulic power generation is also attractive energy resource, since it is said that the estimated amount is 80 % of water power, and that It is difficult to find a place building the large-scale hydroelectric power station in Japan. Recently, research is carried in Faculty of Agriculture University of Miyazaki, using the apparatus of low head ultra-small water wheels in the laboratory and in the small river. In this experiment, the torque and volume flux of water are investigated for several rate of rotation. The wheel geometry is limited in several cases.
Therefore in this thesis, we predict the characteristics of the water wheels by numerical analysis software FLUENT. The flow fields such as pressure and velocity distributions are investigated. The effects of the camber, shape of leading and trailing edge, blade angle and number of blades are elucidated to improve water wheel performance.
