Abstract:

Capillary phenomenon exists widely in human production and life. It originates from the interaction between microscopic molecules, and its influence is manifested at macroscopic level. Exploring the laws of capillary action at the microscopic molecular level can be used to guide engineering practices such as multiphase flow displacement, passive transport in microfluidic chips, and microreactor design, and has important research value. In this review, the research progress of capillary filling dynamics in microchannels is reviewed, and the application of capillary flow in engineering is summarized. The dynamic mechanism of capillary phenomenon is analyzed, and the study of capillary flow is prospected, which provides a reference for the development and application of fluid dynamics theory in microchannels.

Key words: capillary flow, microchannels, microscale, capillary dynamics, interface

摘要:

毛细现象在人类的生产生活中广泛存在,它源于微观分子间的相互作用力,其影响又表现在宏观层面。探究微观分子层面毛细作用规律,可用来指导多相流驱替、微流体芯片中的被动运输、微反应器设计等工程实践,具有重要的研究价值。对微通道中毛细填充动力学的研究进展进行了综述,总结了毛细流动在工程中的应用。分析了毛细现象的动力学规律,并对毛细流动的研究进行了展望,可为微通道中流体动力学理论发展及其应用提供参考。
