中文摘要	An integrated two-fluid model for basic bubbly flows was used to analyze fully developed laminar bubbly flows in vertical pipes. The algorithm overcomes the limitations of the direct discrete difference method, which cannot directly show the reasons for the flow field development. An approximate analytical solution of the two-fluid model was first developed using symbolic integration of the two-fluid model, with the numerical solution then obtained by numerical iterations of the approximate analytical solution. The resulting solution shows that the liquid axial velocity is mainly affected by the drag force, buoyancy force and volume fraction, and that the volume fraction is mainly influenced by the lift force and the wall drag. The numerical solution coincides reasonably well with the experimental data with a prediction accuracy of at least 75%.
