    abstract = {In this study, the three-dimensional bubble
flow in ahorizontal perforated wellbore has been
investigated numerically. Unsteady numerical simulations
of gas-liquid flow in the horizontal wellbore (of ID=
0.0254 m) have been carried out employing commercial
CFD package Fluent 15.1 in conjunction with the VOF
model. The turbulence in the continuous phase was
described by employing k-g model. Air-water is used as
a working fluid in the present work where the air enters
from perforations as radial flow and water enter from the
mainstream as axial flow. The aim of this study to
investigate the effect of axial and radial flow on the
behavior of bubble flow, total pressure drop, void
fraction, and friction factor along the horizontal wellbore.
The main results revealed that the bubble flow pattern can
be seen obviously near the perforations, the friction
pressure drop has more effect on total pressure drop
compared with mixing pressure drop and acceleration
pressure drop, and the void fraction ranges from
minimum value to maximum value (0.04-0.526).}
