基于图像采集与处理方法实验研究了水喷入非相溶油中的液液分散雾化过程.结果表明,通过改变操作条件使水破碎形成3种水滴模式:滴流、层流射流和湍流射流,揭示了其演变规律及其形成机理,获得了分散液体破碎强度、射流长度脉动和液滴粒径分布参数随雷诺数Re、韦伯数We的变化规律.随Re和We增加,分散液体破碎强度持续增强,在Re=467,We=8.6时液滴形成模式由滴流向层流射流发展,在Re=3169,We=241时演变为湍流射流,且液滴的粒径均匀性和最小平均粒径均出现在湍流射流模式下;在滴流模式下,液滴的形成、长大与脱离喷嘴均由液滴受力的平衡机制控制;在层流射流模式下,射流柱破碎形成液滴主要由两相界面的表面波扰动引起,且射流长度的脉动具有随机和非周期的特点;在湍流射流模式下,射流柱表面出现拟序涡结构,其在射流起始段失稳,在射流扩散段大量形成较小粒径的液滴. Based on the method of image acquisition and processing, the liquid-liquid dispersion atomization of water sprayed into the non-miscible oil was experimentally studied. The results showed that water droplets were broken into three kinds of droplets by changing the operating conditions: trickling, laminar and turbulent , The evolution law and the formation mechanism were revealed, and the variation law of the broken liquid strength, the jet length pulsation and the droplet size distribution parameters with the Reynolds number Re and the Weber number We were obtained. With the increase of Re and We, the broken liquid strength With the increase of Re = 467 and We = 8.6, the droplet formation pattern evolves from trickle to laminar jet, evolves into turbulent jet at Re = 3169 and We = 241, and the droplet size uniformity and minimum average particle size In the trickle mode, the formation, growth and detachment of the droplet are all controlled by the equilibrium mechanism of the droplet force. In the laminar jet mode, the droplet of the jet is broken to form the main droplet Which is caused by the disturbance of the surface wave of the two-phase interface, and the pulsation of the jet length is random and aperiodic. In the turbulent jet mode, the pseudo vortex structure appears on the surface of the jet, which is unstable at the beginning of the jet. Large number of segments formed Small particle size droplets.
