Abstract

Pipeline hydraulic transportation is extensively utilized across diverse sectors, with enhancing the performance of pipeline hydrodynamic transport and minimizing erosion wear on the pipeline walls being essential for ensuring the stability of pipeline operations. This paper introduces a methodology for the hydraulic transport of a twisted four-lobed pipe, employing a numerical and erosion model developed through the CFD-DEM (computational fluid dynamics and discrete element method) coupling approach. An experimental circulating flow platform is constructed for validation purposes. The performance of the pipe is assessed by analyzing key indices including fluid velocity, pressure drop, particle trajectory, and erosion wear. The results indicate that twisted four-lobed pipe enhances fluid flow rates, facilitating particle discharge and mitigating accumulation, with reduced wear compared to the twin twist triangle spiral pipe. The analysis of structural parameters’ impact on hydraulic conveyance is also presented. These findings offer theoretical insights for optimizing pipeline performance in hydraulic conveyance while minimizing wear.

基于 CFD-DEM 的扭曲四叶管水力输运特性和侵蚀磨损研究

管道水力输运在各行各业得到广泛应用，提高管道水力输运的性能并最大限度地减少管道壁的侵蚀磨损对确保管道运行的稳定性至关重要。本文采用 CFD-DEM（计算流体力学和离散元法）耦合方法开发的数值和侵蚀模型，介绍了扭曲四叶管道的水力输运方法。为进行验证，还搭建了一个实验性循环流动平台。通过分析流体速度、压降、颗粒轨迹和侵蚀磨损等关键指标，对管道的性能进行了评估。结果表明，与双扭曲三角螺旋管相比，扭曲四叶管提高了流体流速，促进了颗粒排放，减少了积聚，同时降低了磨损。此外，还分析了结构参数对水力输送的影响。这些发现为优化水力输送中的管道性能，同时最大限度地减少磨损提供了理论依据。

期刊介绍： The word ‘particuology’ was coined to parallel the discipline for the science and technology of particles. Particuology is an interdisciplinary journal that publishes frontier research articles and critical reviews on the discovery, formulation and engineering of particulate materials, processes and systems. It especially welcomes contributions utilising advanced theoretical, modelling and measurement methods to enable the discovery and creation of new particulate materials, and the manufacturing of functional particulate-based products, such as sensors. Papers are handled by Thematic Editors who oversee contributions from specific subject fields. These fields are classified into: Particle Synthesis and Modification; Particle Characterization and Measurement; Granular Systems and Bulk Solids Technology; Fluidization and Particle-Fluid Systems; Aerosols; and Applications of Particle Technology. Key topics concerning the creation and processing of particulates include: -Modelling and simulation of particle formation, collective behaviour of particles and systems for particle production over a broad spectrum of length scales -Mining of experimental data for particle synthesis and surface properties to facilitate the creation of new materials and processes -Particle design and preparation including controlled response and sensing functionalities in formation, delivery systems and biological systems, etc. -Experimental and computational methods for visualization and analysis of particulate system. These topics are broadly relevant to the production of materials, pharmaceuticals and food, and to the conversion of energy resources to fuels and protection of the environment.
