Abstract: A model on pressure drop in oil-gas-water threeª²phase slug flow has been set up, which takes account of grownª²proceeding of falling liquid film around Taylor bubbles in slug flow. Based on the experimental study of oil-gas-water slug flow, the numerical simulations of this model agree well with experimental data under the condition of low pressure. The model is an effective method, which can be used for pressure drop of oil-gas-water three-phase vertical upwards slug flow in which the continuous liquid phase is water phase.
Keywords: slug flow, pressure drop, slug unit, falling l iquid film.
