文摘
- •
Four flow patterns (trickling, continuous, semi- and perfect-dispersed) were found.
- •
Pulsing flow regime was observed and analyzed, and the flow maps were presented.
- •
Mechanism of liquid dispersion and its effect on flow resistance were described.
- •
New correlations for the pressure drop of gas–liquid two phase flow were developed.
