Collision Characteristics for Predicting Particle Attrition and Pipe Wear in Conveying Systems

Abstract

Pipe wear and particle attrition are common and undesired effects when conveying particles in pipelines. An approach for predicting these effects to spare considerable efforts spent in trial and error to achieve the optimum operating conditions is reported. The model is composed of a one‐dimensional flow model that calculates the two‐phase flow dynamics, a one‐dimensional breakage algorithm (ODBA) to compute attrition of the particles, and a one‐dimensional erosion model (ODEM) to compute the erosion rate. The ODBA and ODEM exploit machine functions derived from simulations that define collision characteristics. Several collision characteristics were successfully generated universally; therefore, allowing the attrition and erosion models to stand alone in the examined ranges.

Effect of Sand Fines Concentration on the Erosion-Corrosion Mechanism of Carbon Steel 90° Elbow Pipe in Slug Flow

“…Peng and Cao [ 27 ] investigated elbow erosion for multiphase flow and found that maximum erosion occurs adjacent to outlet due to the cumulative effect of sliding and direct impaction. Uzi et al [ 28 ] scrutinized the particle wall interaction of the elbow pipe and concluded that the maximum particle wall collation was at 53° along the curvature despite the particle size. Mansouri et al [ 29 ] investigated numerically and experimentally the erosive wear of elbows configurations for quartz particles.…”
