摘要：VOF method was employed with realizable k-�� turbulence model to predict the influence of structure parameters on liquid film thickness at the outlet of centrifugal nozzle. The numerical result was compared with experimental data to verify the model reliability. The numerical simulation results show that the film is formed into a ring with an air cone in central axis. The liquid membrane is decreased with the increasing of air cone radius, and the length of film broken is shortened by improving flow rate. The bigger the diffusion angle is, the thinner the liquid film is with the shorter of the length of film broken. The bigger the nozzle diameter is, the longer the length of film broken is with unsteady film thickness, and the size of film thickness is floating. The longer the straight of nozzle exit is, the shorter the length of film broken is, while the effect of exit straight length is slight. ?, 2015, Journal of Jiangsu University (Natural Science Edition).
