RESUMO

A new computational model is introduced for describing long-term transient aspects of two-phase vertical flow, focusing the convection phenomenon only. The model uses the concepts ofthe drift-flux model along with specific constitutive relations for bubble, slug and annular flow. The motion of gas is treated with Lagrangean cells, whereas mass and momentum conservation is done upon an Eulerian grid. The model has been adapted to simulate a number of convective transient phenomena occuring in gas-lift wells. The results indicate high versatility and robustness of the model to face severely changing boundary conditions like: varying production rate, sharp changes in the choke diameter and instantaneous shutdown of the flowing well at the surface. The model is specially suited to simulate gas kickand jet-lift operations due to its ability to follow the successive positions of the gas
