Abstract: In this paper some results of research on the liquid film thickness, the dynamic characteristics of wavy surface the airblast atomizers and the relationship between these characterities and atomization characteristics obtained in the past saveral years are sumed up.lt is pointed out especially that there is no liquid accumulation near the atomizer edges.The reason for making erroneous picture about the liquid accumulation is explained.
