An one-dimenssional hydrodynamic model is developed for gas-liquid slug flow in vertical tuee based on the analysis of the flow structure, Some new concepts are adopted for calculating the downward liquid film flow around the moving slug bubble, the void fraction of the liquid slug, and the pressure drop across a slug unit. For air-water system in tubes with tow different diameters, new experimental results are reported and tested by the model. In comparing with other author's model predictions and some previously published experimental data, the model proposed in this work is better than the other models, and the major variables of the slug unit calculated by the model are in good agreement with the experimental data.
