自由空间油池火灾灭火过程仿真研究

Simulation research on free space pool fire extinguishing process

利用FDS软件进行油池火灾水喷淋灭火过程仿真研究。通过大涡计算表明灭火过程中存在最优入射角,并且在一定距离上,增加与火源的距离并不能提高灭火效率,反而会增加消防人员的人身危险,这为消防训练和实际灭火行动提供了理论依据。

Using FDS software the paper simulates and researches the pool fire water spray extinguishing process.By large eddy simulation calculation it shows that the extinguishing process exists the optimal angle of incidence,increasing the distance from the fire source can't enhance fire-fighting efficiency,instead increases the firefighter danger,and provides the theory basis for fire drill and practice fire-fighting action.
