- 摘要:
- 内部流动主要研究了流量系数、液膜厚度和气核半径,分析了内部流场,少量研究涉及内外喷嘴液膜互击、液膜表面波振幅和频率等方面。液液喷嘴外部液膜流动及喷雾特性的研究开展较多,观测了不同工况、结构参数下内外液膜流动形态,少数学者使用理论方法分析了液膜破碎机理。对喷雾特性的研究主要是获得了喷雾锥角、破碎长度、液膜振荡频率等的变化规律,并进一步研究了SMD、液滴速度、混合特性等的变化规律
- Abstract:
- The internal flow mainly studied the flow coefficient, liquid film thickness and gas core radius, and analyzed the internal flow field. A small amount of research has involved the impingement of internal and external nozzles, the amplitude and frequency of the liquid film surface wave. There have been many researches on the external liquid film flow and spray characteristics of liquid-liquid injector. The flow patterns of the internal and external liquid films under different working conditions and structural parameters were observed. A few scholars used theoretical methods to analyze the mechanism of liquid film breaking. The research on the spray characteristics is mainly to obtain the variation of spray cone angle, breaking length, liquid film oscillation frequency, etc., and further study the variation of SMD, droplet velocity and mixing characteristics and so on
