Abstract:
Getting an accurate understanding of the dynamics of multiphase transport for
the design of efficient pipelines is an important issue in the oil and gas
industry. This paper presents simulations of one-dimensional two-phase flow in
pipelines. The compressible model used is derived from the two-fluid model where
pressure relaxation terms are added. The governing system consists of five time-
dependent partial differential equations solved explicitly by a finite volume
approach. Numerical results on well-known air-water compressible flow problems
are performed and analysed. Common problems are observed with coarse meshes and
are reduced with mesh refinement. We conclude that the model and the
discretisation each behave well in regions of large discontinuities of pressure
and velocities.
