【摘要】 随着城市的快速发展环境污染问题越来越严重,开发并利用可再生能源成为社会发展的必然选择,而风能作为一种绿色环保、可再生资源已受到人们的广泛关注。风能与建筑一体化是当前国际上研究的前沿课题,建筑物的风能利用具有免于输送的特点,使产生的电能可直接用于建筑物本身,同时也为绿色节能建筑的发展提供了新思路。本文研究了平板型(单侧圆形开洞和单侧、双侧、上下方形开洞)高层建筑和非流线型(屋顶存在高差的)高层建筑风能利用。通过对比单侧圆形开洞与方形开洞的洞口中心线的风能利用的研究,得到最优的洞口形状,并对该洞口的尺寸进行了优化,此外在该洞口形状的基础上研究了双侧开洞时各风向角下主洞口受辅助洞口的影响其风能利用效能,及上下开洞时各洞口内的风能利用率。对于非流线型高层建筑物,首先分析了平屋顶模型在不同风向角下屋顶各参考点的风能利用,然后研究高差的存在对屋顶各参考点的风能利用效能的影响,得出了屋顶存在高差的非流线型建筑的最佳风能利用位置,并对高差的尺寸进行了优化分析。更多还原

【Abstract】 The problem of environmental pollution is becoming more and more serious, along with the economic development and urbanization in China. It is necessary for China to investigate and utilize the renewable energy resources, but the wind energy superiority causes it to become a present era big subject. Integration of wind energy and building design is one of the frontier research areas. Wind power generation in the built environment can be used to the building itself without power transportation and it provides new ideas for the development of energy-efficient buildings and green buildings.In this thesis, for flat plate and bluff body architecture patterns, such as unilateral circle channel, unilateral square channel, bilateral square channel, high-low square channel and unequal height roof, the wind-energy utilization is mainly studied. By comparing the efficiency of wind energy of unilateral circle channel and unilateral square channel, the perfect channel is obtained. The size of channel is also optimized. Based on the perfect channel, bilateral square channel and high-low square channel is simulated to analyze the wind energy efficiency under different wind directions. For bluff body pattern, wind-energy utilization on the flat roof is analyzed and the wind velocity influenced by unequal height roof is compared. The optimal locations on unequal height roof which benefit wind-energy utilization are gained and the size of height difference is optimized.更多还原
