气溶胶灭火剂烟气流动模拟研究

Simulation study on gas flow law of aerosol fire extinguishing agent

基于优化后的S型气溶胶灭火剂配方,测试烟箱中S型气溶胶灭火剂对梯度火的灭火性能,并通过FDS软件进行仿真,得到了相似的曲线模型。对不同空间位置的气溶胶灭火剂灭火时间进行模拟,得到了相似的曲线模型。模拟气溶胶灭火剂的燃烧最高温度在500~600℃,这与红外成像仪测得的实验数据相吻合。

Based on the optimized S-type aerosol fire extinguishing agent formula,the fire extinguishing performance of S-type aerosol fire extinguishing agent in smoke chamber was tested,the similar curve model was obtained through FDS software simulation.A similar curve model was obtained by simulating the extinguishing time of aerosol fire extinguishing agent at different space locations.The maximum temperature of simulated aerosol fire extinguishing agent is between 500℃and 600℃,which is consistent with the experimental data measured by infrared imager.
