摘　　要：针对冲击式气流喷嘴的雾化特点,考虑气流的冲击作用及表面张力对雾化过程的影响,从液膜受力平衡角度,建立了冲击式气流喷嘴的分阶段雾化模型。分析气流速度、液孔与气孔的相对位置对雾化滴径的影响,模拟结果与实验结果基本一致。Analysising the characteristic of air-blast impingement atomization and considering the influence of drag force and surface tension forces on the atomization,an integrated model of the atomization of air-blast impingement atomizer was proposed by stages based on the equilibrium of force experienced by the liquid ligaments.The model was used to analysis the effect on the drop diameter when the primary velocity of the air or the relative position between the air inlet and liquid inlet was changed.The simulation results agreed well with experiment results.
