... in churn and annular flow regimes for pipe diameters smaller than 0.0254 m (2 in). A simplification of the phase distribution in the churn flow regime is applied in this study such that there is a liquid film flowing upwards (representing net liquid flow rate) on the pipe wall and a gas core, similar...

... entrainment in gas at high pressure. The liquid entrained refers to the fraction of the liquid phase suspended and transported in the gas phase in the form of droplets. Testing was conducted in a 2-inch horizontal pipe and a liquid film removal device was used to obtain the entrainment fraction. Two sets...

... ABSTRACT A model is developed for predictions of wetted wall fraction and gravity center of liquid film in gas-liquid pipe flow under different flow conditions. This model is based on the instability of the liquid film in an equilibrium stratified flow proposed by Taitel and Dukler [1...
