Base on the study and analysis of existing ordinary nozzle and their atomization mechanism, the water mist fire extinguishing nozzle is developed and experimentally studied with Laser Doppler Velocimetry (LDV) and Phase Doppler Particle Analyzer (PDPA). The characteristics of flow coefficient K, atomizing angle , Sauter Mean Diameter (SMD) and the distribution of axial velocity in different test pressure are investigated. We draw the conclusion that the best range of working pressure is 1.5 MPa to 3.0 MPa, SMD is similar to "V" shape, axial velocity is similar to normal distribution, the average of flow coefficient K is 1955.575 and the range of atomizing angle is 60o to 62.8o.
