基于FDS的大型博物馆展厅高压细水雾灭火系统研究

Research on high pressure water mist extinguishing system in large museum exhibition hall based on FDS numerical simulation

采用FDS模拟软件对博物馆展厅进行高压细水雾灭火系统模拟研究,通过对比实体火灾试验的数据,探究了FDS模拟高压细水雾灭火系统的可靠性,并对全尺寸博物馆展厅的高压细水雾系统进行模拟,以期对系统优化进行模拟验证。提出了一种大空间高压细水雾系统设计的优化及验证思路,为其他大空间系统设计提供参考。

The FDS is used to simulate fire extinguishing effect of the high pressure water mist system in the museum exhibition hall.Firstly,the reliability of the FDS simulation high pressure water mist system is explored.Subsequently,the design of the high pressure water mist system based on local test results for the full-scale museum exhibition hall is simulated.Finally,the sys-tem optimization design is simulated using FDS.This paper proposes an optimization and validation approach for the design of large space high pressure water mist system,which can provide guidance for the design of other large space high pressure water mist system.
