红外热成像方法测量火旋风温度的实验研究

Experimental Study on the Fire Whirlwind Temperature Measurment by Infrared Thermography

应用热成像方法获得了火旋风特有的物理现象 ,火焰的大高度直径比 ;并将细水雾作用于火旋风和油池火实验 ;相同的雾通量作用下 ,火旋风能被熄灭 ,油池火却不能被灭掉。由此而对细水雾作用于火旋风的机理进行了讨论 ,对于不同物理形态的火焰 ,细水雾灭火的有效性不同。

Experimental study on the physical phenomenon of the fire whirlwind temperature field by infrared thermography,.the height of the fire whirlwind is more greater than the fire whirlwind diameter.The experiment of the water mist act on the fire whirlwind and the pool fire is done,it is found that the fire whirlwind can be extinguished,but the pool fire of the same size can not be put out with same water mist.The mechanism of the water mist extinguish the fire whirlwind is discussed.The effective measure of the extinction fire is different by water mist extinguish for the different kind form fire.It is raised that the study method of the effective measure that the fire whirlwind is extinguished with the water mist.
