摘要： This invention relates to a computer-implemented method for predicting fluid behaviour in pipeline-based transport systems for transport of multiphase flows involving slug flows which forces one-dimensional CFD models to predict a Taylor bubble velocity being equal to a predetermined Taylor bubble velocity known to be realistic. The enforcement of the 1D CFD model to arrive at the predetermined Taylor bubble velocity is obtained by introducing a force term in the momentum equation for the gas phase at and near the slug-tail top and which is proportional to the difference between the Taylor bubble velocity predicted by the CFD model and the predetermined Taylor bubble velocity. The invention further relates to an autonomous system applying the computer-implemented method.
