... dealing with high liquid holdup. On the other hand, if liquid loading does not occur, an improved two-fluid segregated flow model will be used. The proposed two-fluid model was developed by improving the modeling of wetted perimeters and the liquid wall shear stress. The proposed new two-fluid model...

... fraction. This paper focuses on the liquid viscosity effect on downward gas-liquid flow. Flow patterns, pressure drop, and liquid holdup are measured for downward vertical and near-vertical flow. The acquired data are compared with available mechanistic models, and the discrepancies are discussed. The 2...

In the inclined pipes, Beggs and Brill (1976) conducted a large number of experimental tests to cover different gas/liquid velocities and inclined angles and obtained regression equations to describe liquid holdup and wall friction. Mukherjee and Brill (1980) proposed a very simple...
