| Abstract: | A small scale compartment was built in a confined space in order to study the validity of suppressing alcohol fires by ultra fine water mist.The flame profiles and heat release rates of alcohol fires were examined to study the interaction between ultra fine water mist and alcohol flame.At the same time,the photos of the flame were extracted by high speed camera,and then the Matlab image processing method was used to study the collected fire flame profiles.It was shown that both the mist flux and pre-ignition time may affect the validity of the fire suppression process.In addition,the suppression effect of 200ml/min ultra fine water mist was better than that of 150ml/min ultra fine water mist. |
