中文摘要: |
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。 |
英文摘要: |
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. |
