摘要：

依照现行国家相关标准的规定并参考国外相关标准，对建筑中庭内两类典型设定火灾场景条件下烟羽流的质量流量和温度进行计算和比较分析。建议设计者充分理解和运用中庭烟羽流的发展变化规律，结合中庭自身的建筑特征，有针对性地采取适宜的技术措施，改进和优化中庭排烟系统设计，提高系统的安全性和有效性。

Abstract:

In accordance with the current relevant national standards and with reference to the foreign standards, the mass flow rate and temperature of the plumes have been elaborately calculated and compared under two typical fire scenarios in atrium of buildings. It is suggested that designers should fully understand and utilize the development and change rules of the atrium smoke plume, taking the building characteristics into account,adopt pertinent technical measures to optimize the atrium smoke exhaust system design, so as to improve the effectiveness of the system.

Key words: atrium, plume, mass flow rate, temperature change, smoke exhaust system optimization
