Computational modelling of multiphase flows in process industry Available to Purchase

For wall surface materials, their destruction continues to be associated with a mechanical process of solid particle erosion. The process is attributed to the effect that the entrained solid particles pose on fluids. In process industries such as oil and gas and chemical processes, the phenomenon tends to be encountered more frequently. Some of the effects of erosion include environmental and safety concerns due to oil spills arising from pipe fittings and choke valves, as well as transmission pipeline failures. This paper provides a review of multiphase flows in process industries, offering an introductory insight. The study focuses on previous scholarly investigations that have performed computational fluid dynamics (CFD) simulations under various material viscosity conditions, with a particular focus on multiphase fluids in contexts such as elbow pipes. Also, the review focuses on investigations that have conducted CFD simulations based on Eulerian-Lagrangian method towards multiphase flow modeling. The aim is to give insight into fluid turbulent effects, as well as analyze pressure and velocity distributions for fluid flows. The Stokes number is also considered in the review towards understanding particle motions and their impact. Based on the review outcomes, the paper demonstrates that as the oil velocity increases, there tends to be a marked decrease in erosion rates in multiphase material flows. Also, it is in two main locations in terms of the downstream straight pipe’s side walls and at the extrados closer to the bend exit that there is most occurrence of erosion. With centrifugal forces in play, the review has also discerned that on the side walls, there tends to be unusual erosion distribution
