Calculation on Friction Pressure Gradient of Gas-Liquid Stratified Flows in Condensate Natural Gas Pipeline

Abstract:

Article Preview

Flow characteristics of horizontal two-phase gas-liquid stratified flows in condensate natural gas pipeline are studied through both air-water and air- natural gas condensate experiments on the large-scale multiphase experimental loop. Based on measurement and observation of flow pattern, “apparent rough surface” (ARS) model is selected to calculate frictional pressure gradient with gas-liquid momentum balance equations. The predictions of the models are compared with the data measured in the experiment. Some results of pressure gradient are obtained, so ARS interfacial shape is recommended in horizontal two-phase gas-liquid flows with low liquid loading.
