本文采用风洞试验的方法，研究了密集高层建筑集聚区空气流通和热环境特征。本研究的目的是掌握极密集城市的通风状况，并评估建筑群形式对空气通风的影响。实验结果表明，人行水平风速比的空间平均值可以用建筑总覆盖率的垂直平均值来表示，建筑高度变化对于改善该密集地区的空气流通和热环境非常有效。
In this study, we investigated characteristics of air ventilation and thermal environment in a built-up area with closely-packed high-rise buildings by wind tunnel experiments. The objectives of this study were to grasp the situation of the air ventilations in the extremely dense city, and to assess the influence of forms of building groups on the air ventilation. As the experimental results, spatial average of wind velocity ratios at pedestrian level could be expressed by vertical average of gross building coverage ratio, and the height variation of buildings was very effective for improving the air ventilation and the thermal environment in this dense area.
