Paper Abstract

Water mist is used as an efficient extinguishing media instead of banned halogen-based fire extinguishing agent. Experiment was conducted to study the interaction of fine water mist and a small-scale fire. This fine water mist serves as candidate agent of fire protection system for electronic equipment fire. The characteristics of the fine water mist was obtained by three-dimensional laser Doppler velocimetry (LDV) / adaptive phase velocimetry (APV). Two kinds of fine water mist with equal mean droplet size, different velocity and caliber of mist jet were used to suppress a small-scale fire. A temperature measurement system based on micro-thermocouples was used to record temperature variation of the fire during exertion of fine water mist. A laser Moire deflectometry system displayed the flame pattern. Serial photographs of fire suppression process were present in this paper. The result shows fine water mist offers an enhanced cooling performance on the surrounding of fire flame.
