中庭建筑的回廊排烟策略数值模拟探讨

Numerical Simulation Research of Smoke Exhaust in the Corridor around Atrium of the Building

针对中庭建筑中的回廊,以巴基斯坦某项目为例,采用火灾动力学数值模拟软件FDS(Fire Dynamics Simulation)对中庭中回廊的火灾场景进行数值模拟,模拟内容包括火灾温度场、CO浓度场分布、能见度分布等。通过对烟气蔓延特性的分析和判断,优化中庭建筑中回廊的排烟系统设计。

Through using Fire Dynamics Simulation software, this paper simulates the corridor smoke control system when fire accident occurs in the building with atrium which is located in Pakistan. The simulation results include fire temperature field, the CO concentration distribution field, visibility, etc. Through analyzing smoke spread characteristics, this paper proposes optimum design advices for smoke control design in the corridor of the building with atrium.
