Multiphase parallel flow stabilization in curved microchannel

• The organic–aqueous parallel flow was studied in a curved microchannel with using computational fluid dynamics.
• The effects of guideline structure and surface modification on the flow were investigated.
• The surface modification method shows good flow improvement results.

The effect of liquid multiphase parallel flow stabilizing method (i.e. guideline structure addition and surface modification) was studied in a curved microchannel by using CFD simulation. A phase separator function can be combined within a microchannel by operating under stable parallel flow conditions. Based on our simulation conditions, the flow pattern could not be improved by using the guideline structure but the surface modification proves to be beneficial.
