Simulating two-phase fluid flow in pipeline

A method for building a model to simulate flow of two-phase mixtures, in particular of hydrocarbons, in pipelines, consists in solving equations of conservation of mass for each phase in the mixture and an equation of momentum conservation in the mixture, whilst complying with closing relations, and...

Summary:A method for building a model to simulate flow of two-phase mixtures, in particular of hydrocarbons, in pipelines, consists in solving equations of conservation of mass for each phase in the mixture and an equation of momentum conservation in the mixture, whilst complying with closing relations, and using an explicit solution scheme for the slow waves (corresponding to the gaseous fraction in the pipe) and an implicit solution scheme for the fast waves (corresponding to the propagation of pressure waves). This has the advantage of allowing the time interval to be controlled by the slow waves whilst retaining the same degree of accuracy on these same waves as would be produced with an explicit scheme. The method therefore allows modelling speed to be combined with accurate results, and has a particular application to the design of hydrocarbons pipeline networks.
