Abstract

Abstract:

N₂ bubble formation in highly viscous (630 mPa·s) glycerol-water solution in a microfluidic flow-focusing cross channel device was observed by using a high-speed camera. Bubble forming process, size, and minimal neck radius were studied. The results show that the bubble formation process can be divided into stages of retraction, expansion, collapse, and final breakup. The bubble size was increased linearly with time in both expansion and collapse stages, which the slope in the collapse stage was greater than that in the expansion stage. The decrease of minimal neck radius of bubbles against time was different in two stages, i.e., a power-law to remaining time in the collapse stage and a linearity with time in the final breakup stage.

Key words: microchannels, highly viscous liquids, two-phase flow, bubble, dynamics

摘要：

利用高速摄像仪观察了聚焦十字型微通道内高黏度（630 mPa·s）的甘油-水溶液中氮气气泡的生成过程。研究了气泡生成过程以及气泡体积和最小颈部半径的变化规律。结果表明，高黏流体内气泡生成过程可分为回缩、膨胀、挤压和最终破裂4个阶段。气泡体积在膨胀和挤压阶段均随时间线性增长，但挤压阶段的斜率大于膨胀阶段的斜率。气泡最小颈部半径随时间变化分为两个不同的阶段：在挤压阶段，颈部半径随剩余时间呈幂率关系；而在最终破裂阶段，颈部半径随时间呈线性关系。
