摘要

建筑物发生火灾时

因火灾而伤亡者中大多数为烟害所致。高层建筑中由于存在“烟囱效应”的作用

烟气更容易向上迅速蔓延

而不同的开口状况将影响这种蔓延速度。本文阐述了多层建筑火灾烟气运动的数学模型及数值方法

应用PHOEN ICS3.5对多层建筑火灾产生的烟气运动进行了模拟

分析比较了不同开口状况下火灾烟气的运动状况;同时

初步论述了PHOEN ICS用在建筑火灾烟气运动的数值模拟上的优点和可行性

以及用它来模拟不同开口状况下多层建筑火灾烟气运动的实用性。

Abstract

When a fire occurs in a building

the majority of casualties are caused by fire smoke.In high-rise buildings

because of the stack effect

smoke can easily spread upward

but different states of opening will affect the spread speed.A mathematical model of fire smoke movement in a multi-layer building is described with numerical method as well in this paper.The movement of fire smokes in a multi-layer building is simulated using PHOENICS3.5

and the movements under different states of opening are then compared and analyzed.The advantage and feasibility of PHOENICS used in numerical simulation of fire smoke movement are briefly illustrated.The applicability of numerical simulation of fire smoke movement under different states of opening is also demonstrated.
