| 中文摘要: |
| 为了提升雾化器的雾化性能，对雾化器喷嘴结构进行研究。以空气和水为介质，采用FLUENT软件仿真模拟喷嘴雾化过程并利用试验加以验证。以不同角度的气相出口通道为研究对象，通过调整气压、气液比的大小探究喷嘴在其影响下的喷雾效果。研究结果表明：随着气相通道斜度增大，可以提高喷嘴的雾化质量，当气相通道斜度过大时，也会影响雾化效果；同时，喷雾效果也受气压、气液比的影响，随着气压、气液比的变大，雾滴粒径逐渐变小，雾化性能更好。 |

| To enhance the atomization performance of atomizer, structure of atomizer nozzle was studied. The nozzle atomization process was simulated with air and water as medium by FLUENT software and verified by test; the nozzle spray effect was explored by adjusting the air pressure and gas liquid ratio with different angle of gas phase exits as the research object. The results show that the atomization performance of the atomizer nozzle is improved with the increase of the slope of the air outlet, and the atomization performance is reduced when the slope of the air outlet is too large. With the increase of gas pressure and gas liquid ratio, the drop diameter gradually decreases, and the atomization performance is better. |
