“…However, in the entrance region of the pipe, the distance between the bubbles is not suciently large. The bubbles in this region are in¯uenced by¯ow in the wake of their predecessors, resulting in merging of bubbles and variation of the¯ow structure along the pipe (Moissis and Grith, 1962;Taitel and Barnea, 1990). In order to model undeveloped and transient slug¯ow in entry regions as well as in terrain slugging observed in pipes of variable inclination, detailed knowledge of the¯ow ®eld in the elongated bubble wake becomes essential.…”

“…This force manifests itself as a pressure drop. If the pressure along the liquid film in the bubble zone can be assumed to be essentially constant, this force can be evaluated by the sum of gravity and wall shear stress in the liquid film zone (Taitel and Barnea, 1990). Here the following equations are employed to evaluate the acceleration pressure drop for vertical flow:…”

“…V t is the propagation velocity of the slug unit or average translational velocity of the nose of the slug, given by Taitel and Barnea (1990) 1.2 0.35 The pressure drop due to acceleration takes place in the slug front which penetrates a distances into the body of the slug. The depth of penetration of the liquid film into the slug appears to depend on the relative velocity between slug and film, and may be obtained from the following equation (Dukler and Hubbard, 1975).…”

“…In the past few decades, many numerical codes have been developed to numerically describe slug flow and to compute slugs' characteristics; one of the first methods was the 'unit-cell' approach, which enables a steady-state analysis of a control volume for gas bubbles and liquid slugs [8][9][10]. Issa and Kempf [11] pointed out that "unit-cell" models cannot predict flow pattern transitions; moreover, steady-state models are not necessarily capable of predicting slug flow initiation in inclined pipes due to liquid accumulation.…”
