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

第一年，进行了室外环境分析CFD（计算流体力学）代码的开发和验证，并通过风洞实验建立了室外环境数据库。 1．风洞实验建立室外环境数据库为了有效利用风能，风车建设点的确定非常重要。因此，根据风洞实验对山上的风进行了预测。 2．用于室外环境预测的 CFD 代码的开发和验证对用于预测局部风的湍流模型进行了检查。考虑到地表粗糙度的影响，基于LES（大涡模拟）对二维山丘模型进行了CFD模拟。并进行了基于修正k-ε模型的CFD模拟。第二年，利用第一年开发的室外风环境预测分析系统，进行了风能实际利用规划和风电场原型设计。 1．风力发电站样机的设计与检验制作了小型风力发电能量转换板的缩小模型作为实验。本研究设计的风能转换板不能满足住宅的电力需求，因此该模型被假定为辅助电力。例如照明和通风风扇驱动。对风洞实验预测的电站发电量进行了研究，并根据实验结果对模型进行了改进。 2．风能利用规划利用室外风环境预测分析系统对风能利用规划进行了研究。本研究对风电能量转换板的优化布置进行了验证。此外，还对获得的风能对住宅的节能效果进行了定量评价。较少的
