英文摘要	the hydrodynamics of single-phase liquid flow with relatively high fluid viscosities in a microchannel was investigated experimentally. the results showed that the conventional theory could predict the single-phase flow with high fluid viscosities in microchannels. furthermore, the effect of viscosity on the slug flow of two immiscible liquid phases in a microchannel was studied with high-speed imaging techniques. it was found that a higher dispersed-phase viscosity quickened the flow pattern transition from slug flow to parallel flow and resulted in smaller slugs. a modified capillary number representing the mutual effects of the viscosities of the continuous phase and the dispersed phase was proposed for predicting the slug sizes in microchannels.
