Simulation of transient process in multiphase horizontal pipelines
Based on the two-fluid model, a transient model for the simulation of transient process in multiphase pipelines was developed.The solution of the transient model and the model for stratified flow were discussed.Moreover,a number of experiments including pigging and flow rate changing were conducted on a large multiphase flow loop.The model gave good simulation and accurate predictions for such important parameters as liquid holdup, pressure drop and entrance velocity, which were in agreement with the experimental data, when it was used to simulate the experimental system and real multiphase pipeline.
