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 experimentTo 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 EnvironmentThe 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 … More 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 PrototypeThe 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 EnergyThe 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
