Abstract:

The research of non-equalized system transmission in the microchannel of liquid fluids clarify the mechanism of mass transfer, further improve the efficiency of the quality transmission, and promote the industrialization application of micro-channel devices in the fields of continuous mobile chemical synthesis, biomedical and solvent extraction. The parameters and influencing factors of mass transfer in microchannels are introduced, and the methods and relevant principles are summarized, including the simulation methods for exploring two-phase flow behavior, in-phase and interphase mass transfer, the offline experimental method for evaluating the overall mass transfer performance of microchannel devices, and the online experimental method for real-time detection of the fluid velocity and concentration field in microchannels. The possible development of simulation and experimental methods for the study of mass transfer in liquid-liquid systems in microchannels is also proposed.

Key words: microchannel, multiphase flow, transport, simulation principle, experimental method
