... the superficial liquid velocities varied from 0.005 m/s to 0.1 m/s. Flow visualization at high-pressure was also conducted to verify the flow pattern at high-pressure. Introduction In gas-liquid streams in pipes, the two phases adopt various geometrical distributions known as flow patterns. The flow pattern...

... to churn annular flow (which is around 15 m/s) and at superficial liquid velocities between 0.5 and 2 cm/s. Visualisation of the flow with a high speed camera indicates that the decrease in the pressure drop is due to the more regular nature of the flow when the water is foaming: churning of the flow...
