Abstract：
The particle size distribution of a common air atomizing nozzle with small flow was measured by LSA-Ⅲ laser particle sizer. The experiment was mainly focused on particle size distribution along the different axial position in the condition of different gas-liquid ratio, gas pressure and liquid pressure. The experimental results show that both gasliquid ratio and gas pressure have influence on particle size, the effect of gas pressure is the biggest, then is the gas-liquid ratio and liquid pressure is smallest. According to this experimental condition, the surface area average diameter and volume average diameter of droplet changing at the axial distance of 100 mm, 200 mm, 300 mm, 400 mm and 500 mm are undulatory. By data analysis of the experimental results of droplet size distribution, the characteristic parameters of and n in RosinRammler distribution function could be obtained, and the theory foundation of quantitative calculation for droplet size was provided.
