Abstract:

The good controllability of microfluidic technology provides a new way to prepare high-throughput monodisperse bubbles or droplets. The flow behavior of bubbles and droplets has a great application prospect in the field of materials and has attracted attentions. The research progress on the self-organization behavior of bubbles and droplets in microchannels in recent years is reviewed. The self-organized lattice of bubbles and droplets has periodic flow characteristics, and the self-organization behavior is affected by dispersed phase volume fraction, the size of the droplet or bubble, coalescence effect and channel configuration. The key scientific problems to be solved in the research of self-organization behavior of droplets or bubbles are prospected, which provides a reference for further simulation and experimental research.

Key words: bubble, droplet, self-organization, crystal, microchannels

摘要:

微流体技术良好的可控性为制备高通量的单分散性气泡或液滴提供了新的途径,气泡和液滴的流动行为因在材料领域具有较大的应用前景而受到关注。综述了近年来微通道内气泡和液滴自组织行为的研究进展。气泡或液滴自组织晶格具有周期性的流动特征,自组织行为受分散相体积分数、液滴或气泡尺寸、聚并效应和通道构型的影响。展望了气泡和液滴自组织行为研究过程中待解决的关键科学问题,为进一步的模拟和实验研究提供了参考。
