涉及微通道结构的工艺设备的设计需要详细了解设备内部的流动状况。本文利用高速摄像机的光学流动显示技术,研究了空腔和球形填充方形通道内的流动状态。给出了基于无量纲气体和液体韦伯数预测流型转变的流图和新的关联式。对于极低的气体和液体韦伯数,在所研究的空通道和填充通道中存在分段流型。在分开的隔室中的这种液体流动可以有助于高效接触装置的设计。
The design of process equipment involving minichannel structures necessitates detailed knowledge on the flow conditions inside the apparatus. Here, flow regimes in empty and sphere‐packed square channels were investigated by using optical flow visualization with a high‐speed camera. Flow maps as well as new correlations to predict the flow regime transitions based on the dimensionless gas and liquid Weber numbers are presented. Segmented flow regimes occurred in the studied empty and packed channels for very low gas and low liquid Weber numbers. Such a liquid flow in separate compartments may contribute to the design of highly efficient contacting apparatuses.
