Water mist fire extinguishing technique takes action through oxygen displacement, evaporation cooling and heat attenuation,so as to slow down the chemical reaction and fire spread. The water mist does no harm to the environment. In this study,experiments and numerical simulation on the process and mechanism of the water mist fire extinguishing are carried out.
