Experimental study of the effect of water mist on CH4/air non-premixed flames
Water mist for fire suppression and control has received considerable attention as one of the potential methods for halon replacement. Spatially resolved information on volume mean diameter and coordinate component velocity of water mist has been obtained in two type fine mist, using LDA/APV System. A series of experimental study has been conducted to explore the CH4/air fire suppression effectiveness of water mist. The results show that Water mist consisting of 10-100um water droplets is an effective flame suppressant in a co-flow cup burner flame. The diameter and mass fraction of water mist significantly affects the temperature distribution of the methane CH4/air flame. The effect of oxygen dilution is more prominent in the upper part of the flame, whereas, endothermic heat exchange with the droplets plays a critical role in the lower half of the diffusion flame.
