| 摘 要： | 采用Eulerian-Lagrangian耦合算法,对内混式空气雾化喷嘴的性能参数进行了数值模拟,结果表明:气液质量流量比为定值时,随着喷嘴孔口宽度的增大,雾化角和液滴的速度逐渐减小,索特尔平均粒径(SMD)不断增大;为了获得更细小的液滴,喷嘴孔口宽度不宜过大;喷嘴孔口宽度为定值时,SMD随气液质量流量比的增加,先逐渐减小,达到极小值后,又逐渐增大,喷嘴孔口宽度为0.6mm时,SMD的极小值约为39.5μm。

| Abstract: | Based on Eulerian-Lagrangian coupling algorithm,the performance parameters of Fan-shaped air-blast atomizer is simulated.It is shown that when gas-liquid mass flow ratio is constant,the spray angle and velocity of droplet decreases and SMD increases gradually with the increase of orifice width.Therefore,in order to obtain much smaller liquid droplet,orifice width should not be too wide.When the orifice width is constant,along with the increase of gas-liquid mass flow ratio,SMD decreases firstly and increase... |
