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
