| Research Abstract |
The first year, the development and the verification of CFD (Computational Fluid Dynamics) code for the analysis of outdoor environment and the preparation of the outdoor environmental database by wind-tunnel experiment were performed.
1. Preparation of the outdoor environmental database by the wind-tunnel experiment
To utilize the wind-power energy effectively, the decision of the windmill construction point is very important. so the predictions of the wind over the hill were performed based on the wind-tunnel experiment.
2. Development and Verification of CFD Code for the prediction of Outdoor Environment
The turbulence models for the prediction of local wind were examined. The CFD simulation around the 2-dimensional hill model based on LES (Large Eddy Simulation) was performed considering the effect of roughness on the ground surface. Moreover, the CFD simulation based on the modified k-ε model were performed.
The second year, the plan for actually using wind-power energy and the design

of a wind-power plant prototype were performed using the prediction and analysis system for outdoor wind environment developed in the first year.
1. Design and Examination of Wind-Power Plant Prototype
The scale down model of a small wind-power energy conversion panel was made as an experiment. The wind-power energy conversion panel designed by this research cannot provide the electric-power demand for a dwelling-unit, so the model was supposed as the auxiliary electric power. such as lighting and a ventilation-fan drive. The amount of power generation of the plant predicted by the wind-tunnel experiment was investigated, and the model was improved based on the experimental results.
2. Plan for Utilizing Wind-Power Energy
The plan for utilizing the wind-power energy was investigated using the prediction and analysis system for outdoor wind environment. In this study, the verification of optimum arrangement of the wind-power energy conversion panel was conducted. Moreover, the enerty-saving effect of obtained wind-power energy for the residence was also evaluated quantitatively. Less
