高层建筑火灾烟气流动性状的数值模拟

Numerical simulation of fire smoke flow properties in high-rise building

作者根据高层建筑火灾烟气流动的特点,应用火灾烟流模型和计算机网络模型,在CFX软件支持下,对高层建筑火灾烟气流动性状进行数值模拟,该模拟计算为高层建筑安全及火灾救援提供理论依据。通过模拟计算可以得出任意时刻高层建筑各部位的温度、压力、烟气浓度及开口处流量。利用模拟计算结果,可以评价高层建筑整体或局部火灾安全性能,制定科学的应急救援预案,提供救灾决策支持信息。

According to the characteristics of high-Rise building fire smoke flow, based on CFX software, the fire smoke flow properties in high-rise building is simulated by using fire smoke flow model and network model. According to the simulation, the theory of highr-rise building fire safety and fire resuce is set up. The temperature, pressure, smoke concentration and flow-rate at a place of the high-rise building can be obtained by simulating. With the simulation results, the whole or local fire safety property in the high-rise building can be evaluated and emergency saving scheme can be scientifically made, useful information for establishing aid way is provided.
