Numerical simulation of isothermal gas−liquid flow patterns in microchannels with varying wettability

- Gas−liquid flow patterns were modeled in microchannels.
- The effect of the wall wettability on the gas−liquid flow pattern was investigated.
- Taylor flow was observed in the hydrophilic microchannel.
- Stratified flow was observed in the hydrophobic microchannel.
- The numerical data agreed with experimental reference and correlations.
