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的CFD（计算流体动力学）代码的开发和验证，并通过风洞实验制备了室外环境数据库的准备。1。风洞实验制备室外环境数据库，可以有效利用风车施工点的决定非常重要。因此，根据风能实验进行了对山上风的预测2。研究和验证CFD代码用于预测室外环境的湍流模型，以预测当地风。考虑到粗糙度对地面的影响，进行了基于LES（大涡模拟）的二维山丘模型周围的CFD模拟。此外，进行了基于修改的K-ε模型的CFD仿真。第二年，实际使用风能能量和设计的计划……使用了第一年开发的室外风环境的预测和分析系统，进行了更多的风力植物原型。1。一项实验，对风力植物原型尺度的设计和检查是小型风能转换面板的模型。这项研究设计的风能能源转换面板无法为住宅单元提供电力需求，因此该模型被认为是辅助电力。例如照明和通风驱动器。研究了通过实验结果改善了通过风能隧道实验预测的植物的发电量。2。利用风能能量的计划使用室外风环境的预测和分析系统研究了利用风能能量的计划。在这项研究中，进行了风能转换面板的最佳排列验证。此外，还定量评估了该住宅中获得的风能能量的节能效应。较少的
