摘    要:多相微反应器等微通道设备具有高效、安全等优势与广阔的应用前景,其中气泡分散相的形变、聚并、破裂等诸多流体力学行为对反应体系具有非常重要的影响,然而由于微通道的尺度特征以及多相流动非均匀性、复杂性等特点,复杂限域结构内的气泡形变与破裂机理认识仍不够充分。本文针对近年来在微尺度限域结构中的气泡形变与破裂等研究进展进行综述,首先概述了微通道多相流主要研究对象及研究方法,探讨了含有颗粒等受限狭窄空间及复杂多相条件下的传递机理研究进展,总结了气泡界面演变及不稳定破裂过程的多相相间作用机制。最后,提出研究体系构建、研究方法改进、相间作用解析以及工程化需求匹配是微尺度复杂限域空间内的气泡行为研究关键,并对下一步研究方向进行了分析与展望。

关 键 词:微反应器  气泡  破裂  颗粒  界面不稳定性

Abstract:Microchannel devices, such as multiphase micro-reactors, have extraordinary advantages and broad prospects for application. The hydrodynamic behaviors of the dispersed phase play an important role in the transport and reaction process, while the transport mechanism research of complex systems containing particles is still deficient. In this paper, the research progress of bubble deformation and breakup in micro-scale confined structures in recent years is reviewed. The main research objects and research methods of multiphase flow in microchannels, especially the transport mechanism in confined space containing particles or other complex multiphase conditions, are summarized. The interaction mechanisms of bubble interface evolution and unstable-breakup process are discussed. Finally, the future directions of bubble breakup under the influence of confined structures are analyzed and prospected.
Keywords:microreactor  bubble  breakup  particle  interface instability
