... revealed that the model over-estimate the critical gas velocity compared to results where entrainment is neglected. 1 INTRODUCTION Most gas wells produce liquid as co-produced fluid during well production. Liquid flows along with the gas core as droplets or liquid film on the tubing wall...

... film can become very rough, significantly increasing the frictional contribution to the pressure gradient; this is particularly significant for flows with low liquid loading, where other contributions to the pressure gradient are relatively small. water cut gas core production monitoring...
