Fremgangsmåte for bestemmelse av strømningsparametere for en flerfasestrømning i en rørledningsseksjon

摘要

This invention relates to a method for transient quasi three-dimensional simulation of multiphase fluid flow in pipelines by employing a hybrid numerical model which treats different continuous fluid phases as separate phases coupled together by local boundary conditions at large scale interfaces and which treats dispersed phases within the continuous phases as dispersed fluids according to the drift flux concept.
