A Study on CFD Analysis of Sand Erosion in a Pipeline
Keywords:
Sand erosion, Pipe erosionAbstract
Elbows are extensively brought in use for gas as well as oil extraction pipelines, power plants, refineries, ammonia gas plant, etc. One of the major challenges which are present further industry of petroleum is the erosion of the pipelines. There are five financial integrity and threats available related to the safety of the pipeline because of the issue of erosion. The pipe system’s performance is influenced because of the pipelines erosive issues. This demands rapid arrangements of elbows because of the restrictions of the external spaces as well as there is a shortage among the elbows in respect to their connection length. The erosion characteristics and the flow field of the elbows connection gets influenced because of the interactions among the two elbows. This paper targets for investigating the behavior of the sand erosion six in the pipeline elbow under different fluid mediums such as methane, diesel and water Along with the sand Oklahoma number 1 in a pipe of 76.2-millimeter dia. This investigation is done with the help of computational fluid dynamics. Therefore, the use of CFD analysis with approach of Eulerian-Lagrangian is made for solving continuous phase with the help of “Navier stokes equation” and used “particle force balance” for solving the second phase. For modeling the continuous fluid phase’s turbulence behaviour so that it can address the “viscous boundary effects” in the elbow’s secondary flow and near wall region and attain more precise outcomes, “low Reynolds number correction” and Reynold stress model is brought in use.
