.... This objective is achieved by proposing a liquid viscosity-dependent sheltering coefficient model into the Taitel and Dukler (1976) stratified-smooth/stratified-wavy transition model. Further objective is to propose a new slug/annular transition criterion in horizontal and slightly inclined two-phase flow...

... Abstract Majority of existing flow regime transition models do not identify the existence of plug and mist flows. Also, these models are applicable to either vertical or horizontal flow. Further, experimental data in literature show that the model of Taitel and Dukler (1976) under predict...

... and the gas phase on the top. Taitel and Dukler (1976) sub-divided the stratified flow into stratified-smooth (SS), where the gas liquid interface is smooth, and stratified-wavy (SW), occurring at relatively higher gas rates, at which stable waves form at the interface. Shoham (1982) performed a systematic...

... predict which holdup solution is going to happen in reality, and at which conditions the sudden change in holdup will take place. One of the first studies to point out the occurrence of multiple solutions under certain conditions in the original two-phase stratified flow model presented by Taitel...
