英文摘要	the miscible liquid-liquid two phases based on taylor flow in microchannels was investigated by high-speed imaging techniques and villermaux/dushman reaction. the mixing based on taylor flow was much better compared with that without introducing gas in microchannels, even the ideal micromixing performance could be obtained under optimized superficial gas and liquid velocities. in the mixing process based on taylor flow, the superficial gas and liquid velocities affected the lengths and the velocities of taylor bubble and liquid slug, and finally the micromixing performance. the formation process of taylor flow in the inlets, the initial uniform distribution of reactants and the internal circulations in the liquid slug, and the thin liquid films all improved the mixing performance. furthermore, a modified peclet number that represented the relative importance of diffusion and convection in the mixing process was proposed for explaining and anticipating micromixing efficiency.
