A new pressure gradient correlation for oil-water dispersed flow in horizontal pipes

چکیده مقاله

This study presents a new pressure gradient correlation for oil-water dispersed flow in horizontal pipes. The new model was derived from 225 experimental pressure gradient data points for variety range of Reynolds number (Rem =2300- 1×105) and mixture velocities (Um=0.5-4 m/s). The accuracy of this new model has been evaluated against the homogeneous model. The comparison indicates that the new proposed correlation predicts the pressure gradient with higher accuracy than the homogeneous model.
