| 摘 要： | 综述了微通道内的气液两相流行为及传质特性。在微通道内流型一般分为泡状流、弹状流、环状流和弹状-环状流,没有分层流。气液传质效率比常规尺度中的提高了2～3个数量级。讨论了气泡对气液两相流的影响及其生成、生长和聚并规律。介绍了微通道内气液两相流的计算机模拟结果。从实验、理论和数值模拟3个方面对微通道内气液两相流的研究和应用前景进行了展望。

| Abstract: | The gas-liquid two-phase flow behavior and mass transfer characteristics in microchannels are reviewed.The flow patterns in microchannels could be divided into bubbly flow,slug flow,annular flow and slug-annular flow,but no stratified flow,and the mass transfer efficiency increases by 2-3 orders of magnitude over that in conventional-sized devices.The formation,growth and coalescence of bubbles and their effect on gas-liquid two-phase flow in microchannels are also discussed.The progress of numerical simulation of gas-liquid two-phase flow in microchannels are introduced briefly.The research and application prospects of gas-liquid two-phase flow in microchannels are predicted from the aspects of experiment,theory and numerical simulation. |
