| 摘 要： | 运用Fluent软件模拟了低压旋流喷嘴下游流场喷雾情况。利用欧拉-拉格朗日模型模拟气液两相耦合流动。模拟显示:喷嘴喷雾形状为空心锥状,与实验得到的喷雾形状相符。喷雾的液滴速度分布于15～25m/s之间,且随轴向距离的增大而减小;喷雾的液滴直径沿轴向距离增大而增大。

| Abstract: | The paper simulated the downstream flow field atomization situation of low-pressure swirl nozzle by using Fluent software. The Euler-Lagrangian models were applied to simulate gas-liquid two phase coupled flow. And the simulation results show that when atomizing liquid spray with hollow cone shape accords with experimental results. The droplet velocity ranged from 15m/s to 25m/s decreases with the spray particle diameter increases; however, diameter of the spray droplet will be increased with the increasing of axial distance along the axle. |
