To improve the atomization effect of multiple nozzles in snowmaking machines，a 3D transient multiphase flow model was constructed using the discrete phase model （DPM） and the Taylor analogy breakup （TAB） model.Combined with experimental validation，the variation laws of atomization characteristics under linear，circular，right triangular，and equilateral triangular nozzle arrangements were systematically analyzed.Meanwhile，the regulatory effects of installation height and spacing differences on atomization characteristics were investigated.The results indicate that on the same plane，the equilateral triangular and circular arrangements exhibit good and similar distribution uniformity.Among them，the equilateral triangular arrangement has a larger sauter mean diameter SMD （94.31 μm） and better atomization effect.For the right triangular arrangement，the proportion of large‑sized droplets in the far‑field region reaches 72%，showing a stronger droplet coalescence effect.The linear arrangement has the smallest SMD （92.8 μm），achieving the best droplet breakup effect.Meanwhile，differences in nozzle installation height and spacing have a limited impact on the overall atomization characteristics but can effectively regulate atomization interference behavior.The research results reveal the influence mechanism of nozzle geometric layout on the synergistic atomization characteristics of multiple nozzles，providing a reference for the layout design of snowmaking machine nozzles.
