Abstract EN
A water-organic slug flow in a T-shaped microchannel was numerically studied due to its importance in the microreactor system.
Various factors affecting the flow mode were studied, for example, channel width, fluid viscosity, interfacial tension, and inlet velocity.
The volume of fluid (VOF) method was used to track the liquid-liquid interface, and the piecewise-liner interface construction (PLIC) technique was adopted to get a sharp interface.
The interfacial tension was simulated with continuum surface force (CSF), model and the wall adhesion boundary condition was taken into consideration.
The results show that strong vortexes appear in both phases at the meeting sites of main and lateral channels where an organic slug is producing.
Inlet velocity influences the slug length and flow mode greatly.
The ratio between the slug lengths of two phases in the main channel is almost equal to the ratio between their inlet velocities.
If the slug is produced, the interfacial tension and organic viscosity have less effect on the slug length for 200 µm microchannel.
The slug producing rate is much higher in a narrow channel than that in a wide channel.
