| 中文摘要 | 使用激光相位多普勒分析仪PDA对旋转型气-液雾化喷嘴的雾化特性进行了实验研究。使用水代替油作为被雾化的液体,采用压缩空气作为雾化介质,测量了不同工况下的喷雾特性参数,如喷雾液滴粒子的索太尔平均直径SMD和粒子速度等。实验测量结果表明,喷嘴在较小的气液比条件下可以达到较好的雾化状态,中心的液滴平均SMD可以达到40μm。随着压力和气液比的增加,雾化水平也随之提高,但是受喷嘴结构的影响很小。本文的研究为喷嘴的实际设计提供了基础依据。; By using a laser-phase Doppler analyzer (PDA), an experimental study was conducted of the atomization characteristics of “Swirling Gas-liquid Spray Atomizers”. Water was used as the liquid to be atomized instead of oil and compressed air employed as an atomization medium. The parameters of atomization characteristics under different operating conditions were measured, such as Sotyl mean diameter and particle speed of atomized droplet particles etc. The experimental measurement results indicate that the atomizer can achieve a comparatively good atomization state under the condition of a relatively small gas-liquid ratio with the average SMD of droplets at the center reaching 40 μm. With an increase in pressure and gas-liquid ratio, the atomization level will be enhanced accordingly. However, it is scarcely affected by the structure of the atomizer. The research findings can provide an underlying basis for the practical design of atomizers. |
