Abstract Elbows are important fitting components used to change the flow direction, and they widely in pipeline transport systems. In this work, an experimentally validated Computational Fluid Dynamic (CFD) approach is investigate erosion prediction gas-solid flows 3-inch (76.2 mm) standard elbows (r/D = 1.5). The length between two varies from 2 50 times pipe diameter. First, a mesh independence study was performed minimize uncertainty related size on predictions elbows. Second, different...
Abstract Solid particle erosion is an important subject when it comes to pipelines carrying solid particles in mining and oil gas operations sand production occurs. For that, predict that occurs maintain equipment integrity, the phenomenon has been widely investigated over recent years. multiphase (gas-liquid-sand) flows, affected by superficial liquid velocities, size shape, flow regime. This work aims investigate effect on of two cases with similar mixture velocity but different velocities...
Abstract Elbows in series are commonly encountered various piping systems on oil and gas subsea platforms. In numerous fields, solid particles entrained with produced fluid causing particle erosion of these elbows. Therefore, was examined two standard ID 3-inch (76.2 mm) elbows series. The distance between the is twice pipe diameter (2D). Firstly, paint removal studies were performed to identify location maximum second elbow superficial (air) liquid (water) velocities 31 m/s 0.1 m/s,...
Abstract The oil and gas industry faces significant challenges due to solid particle erosion in various pipe fittings equipment. Solid occurs when particles that are entrained produced fluids impact the wall of pipeline fitting parts. In order reduce components, different or modified geometries can be introduced mitigate particles. Using long-radius elbows, for example, instead standard elbows has been shown prevent failure elbows. Due conducting experiments multiphase flows involving...
Abstract The erosion resistance of five types tungsten carbides (with various material hardness) and stainless steel 316 (SS316) were experimentally investigated in sand-air flows. primary purpose this work was to evaluate the effect materials' surface hardness on resistivity different samples at impact angles velocities. A gas-sand loop consisting a compressor, sand feeder, nozzle, pressure regulator developed create gas flows contaminated with solid particles. Before performing...
