摘要: 宾馆酒店业的蓬勃发展带来的不仅仅是经济的收益,还有许多的火灾事故安全隐患。为了掌握研究此类建筑室内火灾过程中的规律与特性,进行了对某宾馆火灾过程的场模拟研究。通过使用了火灾模拟软件SMARTFIRE来对某栋5层楼的宾馆进行火灾模拟,改变其物理参数例如火源位置、数量和通风状况来进行对比,研究温度场、烟气蔓延程度等数据结果。得出了在火灾过程中烟囱效应会很大影响火灾的烟气蔓延情况;多个火源数量的火灾较之于单个火源数量的火灾,整个过程的时间更短,过程中产生的烟气量会更多以及蔓延的速度更快;通风状况对火灾过程中火源发热曲线速率有控制作用。69789

A simulation study of a hotel fire process
Abstract: The boom in hotel hospitality is not just an economic gain, but a lot of fire safety hazards. In order to study the regularity and characteristics of such indoor building fire, a simulation study of a hotel fire process was carried out. By using the simulation software SMARTFIRE to make a five floors hotel fire simulation, change its physical parameters such as fire location, quantity and ventilation condition to compare, research results and the degree of spread of the flue gas temperature field data. It is concluded that the chimney effect can greatly influence the spread of smoke in the fire. ; multiple source number compared with the single number of fire , the process time is shorter, the process of the spread of smoke volume more and more quickly ; the ventilation condition has the control effect on the heat curve rate during the fire.
