“…horizontal pipe using oils of various viscosities were used to attempt validation of the model. This work extends previous horizontal three-phase studies reported on flow regimes [17] and hold-up [18] to include the pressure-drop data for the same apparatus. A momentum-balance model is developed in order to attempt to predict three-phase flow pressure-drop phenomena.…”

Pressure-loss data are reported for three-phase oil-water-gas flow in horizontal pipes of 0.0259 and 0.0501 m i.d. The pressure profiles exhibited a maximum value above a critical gas rate, which progressively moved to higher oil ratios as the gas rate was increased due to increased turbulence within the system. The actual pressure-drop profiles obtained depended mainly on the flow regimes present within the system. As the pipe diameter was reduced, the pressure drop was observed to increase for the same flow conditions. Above a critical gas rate the magnitude of the pressure drop was higher if approached for the oil-dominated (OD) region compared to the opposite direction.A momentum-balance model was proposed for prediction of the pressure drop, which gave improved performance over other existing methods. 

Results are presented on three-phase air/oil/water horizontal flow in a 0.026 m i.d. symmetrical impacting tee junction. The flow regimes observed agreed with an existing three-phase flow map. The inversion from waterdominated (WD) to oil-dominated (OD) flow was at an oil-to-liquid volumetric ratio of f o = 0.285. The inversion was at a low f o value because of the relatively tranquil conditions studied. Retention of oil on the pipe wall at the air/water two-phase condition at f o = 0 resulted in a dramatic increase in the pressure drop above that expected for the two-phase flow. The pressure drop in the tee junction arms increased with liquid-flow rate. The actual tee junction pressure drop showed a similar pattern to that observed in the inlet arm. The pressure drop was relatively constant in the OD region but showed a dramatic increase in the WD and inversion regions at low f o values. Non-dimensionalising the junction pressure drop as l e /d gave a similar pattern but the scatter of data increased.The tee pressure loss data were modelled using the Lockhart-Martinelli G parameter and gave similar but different correlations for the WD and OD regions. 

Dispersed oil–water–gas flow through a horizontal pipe

et al. 2009

An experimental study of three‐phase dispersed flow in a horizontal pipe has been carried out. The pressure drop over the pipe strongly increases with increasing bubble and drop volume fraction. Because of the presence of drops the transition from dispersed bubble flow to elongated bubble flow occurs at a lower gas volume fraction. The gas bubbles have no significant influence on the phase inversion process. However, phase inversion has a strong effect on the gas bubbles. Just before inversion large bubbles are present and the flow pattern is elongated bubble flow. During the inversion process the bubbles break‐up quickly and as the dispersed drop volume fraction after inversion is much lower than before inversion, a dispersed bubble flow is present after inversion. (When inversion is postponed to high dispersed phase fractions, the volume fraction of the dispersed phase can be as high as 0.9 before inversion and as low as 0.1 after inversion.) © 2009 American Institute of Chemical Engineers AIChE J, 2009
