基于“气旋”的中庭防排烟优化设计

Optimization Design of Smoke Control and Exhaustion in Atrium based on "Cyclone"

本文提出一种新型的、基于"气旋"机理的中庭结构防排烟优化设计,并通过FDS(fire dynamics simulator)软件模拟,对比两种防排烟模式的效果。模拟结果表明:采用新型防排烟优化设计能够使得中庭顶部排烟速率提高1倍,模拟得到的结果对于中庭结构的防排烟有着巨大的实用价值。

This paper proposed a novel optimization design of smoke control and exhaustion in atrium structure basedon 'cyclone' mechanism, and through the FDS software simulation compared the effects of two smoke control and ex-haustion modes. The simulation results showed that the optimization design of the new smoke control and exhaustioncan make the top smoke exhaustion rate of the atrium get a double increase. The simulation results have a great practi-cal value for the smoke control and exhaustion of the atrium structure.
