摘要: 旋转湍流场中液滴的分散特性是流体机械设计优化过程中的难题。采用新型同心旋转圆筒装置获得了均匀分布的旋转湍流场,在Hinze模型的基础上考虑了分散相黏度对油滴分散特性的影响,对旋转湍流场和油滴分散特性的关系进行了初步探讨,获得了雷诺数为5.5×104~2.4×105,相对离心力为21.9~643.3时,流场特性与油滴分散特性的经验关系式,完善了旋转湍流场内油水分散特性的研究,为旋转湍流场内液⁃液分散特性提供新的研究思路。

Abstract: The dispersion characteristics of droplets in swirling turbulent flow field is a difficult problem in the process of fluid mechanical design and optimization. A new concentric rotating cylinder is used to obtain uniformly distributed flow field. On the basis of Hinze's model, the influence of oil droplet viscosity on oil droplet dispersion characteristics is considered. The relationship between turbulent flow field and oil droplet dispersion characteristics is preliminarily discussed. The empirical relationship between flow field characteristics and oil droplet dispersion characteristics is obtained when Reynolds number is 5.5×104~2.4×105 and relative centrifugal force is 21.9~643.3.The research on dispersion characteristics of oil and water in swirling turbulent field is improved, which provides a new research idea for the liquid⁃liquid dispersion characteristics in swirling turbulent flow field.

Key words: Concentric rotating cylinder, Flow characteristics, Oil droplet dispersion characteristics, Numerical simulation
