Numerical Modeling of Two-Phase Liquid-Solid Movement through Pipes

The oil industry is that branch of the world economy that provides energy resources for humanity and the transition to energy produced from renewable resources. That is precisely why the study of mass transfer (the transport of petroleum fluids through pipelines) represents one of the primary activities in scientific research; the role of this discipline is to provide theoretical support to understand the phenomena that govern these technological processes. One of the industrial applications of multiphase transport is the movement of multiphase fluids (liquid-solid) through pipes and especially the phenomena of separation of these phases. Due to the depletion of oil and gas resources associated with deposits discovered before 1990, the extraction of these petroleum fluids faces the presence in the composition of large amounts of sand, salt or paraffin (solid phase), dissolved solids, and present in the liquid phase, which makes the activity of separating, removing and cleaning petroleum fluids from associated sediments, an increasingly present and functional industrial activity for the development of oil and gas exploitations. That is precisely why a work that analyzes the numerical modeling of the separation process and the simulation of the solid-liquid transport processes through the central pipeline systems is necessary for the economic and detailed design of the machines associated with this industry. This paper analyzes the behavior of various solid substances in the flow of petroleum liquids. As a result of the laboratory data, we created a numerical model associated with these two-phase flows.
