Abstract：In this paper，the spray charactersitics of a three flow passangers air-liquid-air critical airblast atomizer were studied. Some data and curves were achieved about the effects of geometric structures, operational pressure air/liquid ratio , rate of flow etc. on particle's mean diameter MDD at the same time. Some significant spraying regularities of this type of a atomizer weredeveloped and gotten. It can give some basis and a way for the spray of highly viscous or easy solidfing or wearing liquids to get fine particies.

Keywords: critical airblast ;atomizer.
