Title: | 气体介质中双元液滴的碰撞动力学 | Other Title: | Dynamics of binary droplet collision in gaseous environment | Authors: | He, CM Zhang, P |
Issue Date: | 2017 | Source: | 中国科学: 物理学 力学 天文学 (Scientia sinica (physica, mechanica & astronomica)), 2017, v. 47, no. 7, 070013 | Abstract: | 本文简要综述了气体介质中双元液滴的碰撞动力学的研究进展,重点在于揭示这个问题的多尺度、多物理、非线性的特性。本文首先介绍了各种气体和压力下双元液滴碰撞的实验现象。然后讨论了完全等同的两个液滴的正碰这一最简单的情形的理论分析。最后介绍了大小不同液滴的融合和混合、非牛顿流液滴的碰撞等近年关注度较高的问题。 This review aims to briefly discuss about the research progress of the dynamics of binary droplet collision in gaseous environment, with emphasis on revealing the multi-scale, multi-physics, and nonlinear characteristics of the problem. First, we reviewed the previous experiments on binary droplet collision in various gases of sub-and super-atmospheric pressures. Second, we highlighted several theoretical models accounting for coalescence, bouncing, and separation of identical droplets. Finally, we discussed the recent studies on droplet coalescence and subsequent mixing, and non-Newtonian droplet collision, which have been gained increasing interests. |
