研究了微流控回路中2-氨基-2-甲基-1-丙醇（AMP）和乙二醇（EG）吸收CO2的气液两相流分布和传质性能。观察到四种流型：过滤流、再分配流、破碎流和不规则流。结果表明，T形接头处气泡长度和下游通道的水动力反馈共同影响流量分配的均匀性。同时，均匀的流量分布有利于传质性能。在此基础上，考虑表征流量分布不均匀性的相对误差Er，建立了平行微通道内破碎流条件下液体侧体积传质系数的预测模型。
The gas-liquid two-phase flow distribution and mass transfer performance of CO2absorption into 2-amino-2-methyl-1-propanol (AMP) with ethylene glycol (EG) in two parallelized microchannels in a microfluidic loop were investigated. Four flow patterns were observed: filtering flow, repartition flow, breakup flow and irregular flow. The results showed that the uniformity of flow distribution is jointly affected by bubble length at T-junction and the hydrodynamic feedback of the downstream channels. Meanwhile, the uniform flow distribution facilitates the mass transfer performance. Furthermore, a prediction model of liquid side volumetric mass transfer coefficient under breakup flow in parallel microchannels was established by considering the relative errorErcharacterizing the flow maldistribution.
