| 摘 要： | 对三通道气力式喷嘴进行了雾化室加压环境下的雾化试验研究,分析了雾化室环境压力与其他喷嘴运行参数对喷嘴雾化性能的影响。研究发现,雾化室环境压力的提高有利于气液两相的相互作用,可以有效降低雾化粒度平均直径,且当气耗率不变时,雾化粒径SMD与雾化室环境压力呈负指数的幂函数关系。

| Abstract: | The atomization property of airblast three-channel nozzle under high ambient pressure was investigated.It was found that continuous increase in air pressure caused the decrease of the mean drop size to a minimum value and then varied not too much.An explanation for this characteristics was provided in terms of the various contributing factors in different process of atomization.The results showed that SMD was proportional to Pn at a constant air/liquid ratio. |
