摘要
本文概述了空气流经建筑物时的物理特性，总结了国外在数值模拟方面的进展，特别是ｋ － ε模型的优缺点，并在此基础上指出了今后研究的发展趋势。
The physical characteristics of the airflow around a building were reviewed first in this paper. Then, the advance in numerical simulation of the flow was summarized, especially the advantages /disadvantages of k-ε models. Finally, the developing trends were discussed at the end of this article.
