摘要:: 【目的】能源转型背景下氢能管道的建设已成为必然趋势，虽然管输介质正在向氢气转变，对氢气携带颗粒造成的管道冲蚀问题的研究仍旧缺乏。借助天然气站场内杂质颗粒粒径和质量流量数据对站场氢气管道弯头冲蚀问题进行研究有利于保障氢气管道的安全运行。【方法】针对氢气与天然气站场弯头冲蚀磨损差异性问题，基于DPM模型采用Fluent软件建立数值模型，模拟了弯径比为1.5的DN200管道90°弯头的冲蚀过程。研究了流动方向、气体组分、气体流速、杂质颗粒直径以及杂质颗粒质量流量对冲蚀磨损形貌与速率的影响。同时利用用户自定义函数（User-Defined Function，UDF）提取了壁面处颗粒碰撞信息，分析了撞击角度、撞击速度以及撞击频次耦合作用对冲蚀形貌以及冲蚀速率差异的影响。【结果】冲蚀严重区域主要存在于直管段以及弯头出弯段内、外弧面且随颗粒斯托克斯数变化而移动；纯氢站场内弯管最大冲蚀速率随着流体流速的增加而呈指数关系增大，随质量流量增加而近似呈线性增长趋势，随粒径增加先缓慢增长后快速增长双阶段特征；相同能量供应强度下管输介质为氢气时弯管最大冲蚀速率远大于甲烷；纯氢管道存在临界粒径为30 μm，杂质颗粒粒径超过临界值后弯管最大冲蚀速率增长趋势会显著增高；当管内颗粒物浓度小于100 mg/m³、粒径小于10 μm时，氢气站场内流速可提高至30 m/s而不对管道安全性产生显著影响。【结论】通过多尺度耦合分析，阐明了氢气管道的冲蚀机制，明确了介质物性、颗粒动力学的交互作用对冲蚀行为的影响规律，为氢气站场流速与杂质含量规定提供理论参考，能够降低站内弯头失效风险，为氢能基础设施的可靠性设计与标准制定提供理论基础。

Abstract:: [Objective] The construction of hydrogen energy pipelines is an essential trend in the context of energy transition. Despite the shift in pipeline transportation to hydrogen, research on erosion caused by particles in hydrogen remains limited. Investigating the erosion of hydrogen pipeline elbows using data on impurity particle size and mass flow in natural gas stations is crucial for ensuring the safe operation of hydrogen pipelines. [Methods] Regarding the difference in erosion wear between hydrogen and natural gas pipeline stations, a numerical model was established using Fluent based on the DPM model to simulate the erosion process of the 90° elbow of DN200 pipelines with a bend-to-diameter ratio of 1.5. The effects of flow direction, gas composition, gas flow velocity, impurity particle diameter, and impurity particle mass flow rate on erosion wear morphology and rate were examined. Additionally, a user-defined function (UDF) was utilized to extract particle collision information at the wall surface, allowing for the analysis of the coupling effects of impact angle, impact velocity, and impact frequency on differences in erosion morphology and rate. [Results] Severe erosion areas were predominantly found in straight pipeline segments and on the inner and outer arc surfaces of the elbow exit segments, shifting with changes in particle Stokes number. In pure hydrogen stations, the maximum erosion rate of the elbow increased exponentially with fluid flow velocity and approximately linearly with mass flow rate. The erosion rate also exhibited a two-stage characteristic, initially increasing slowly before rising rapidly with increasing particle size. When the pipeline transportation medium was hydrogen, the maximum erosion rate of the elbow was significantly greater than that of methane pipelines under the same energy supply intensity, with a critical particle size of 30 μm identified for the pure hydrogen pipeline. Beyond this critical value, the elbow’s maximum erosion rate exhibited a marked increase. Additionally, when the concentration of particulate matter in the pipe was below 100 mg/m³ and particle size was under 10 μm, the flow velocity in the hydrogen station could reach 30 m/s without significantly compromising pipeline safety. [Conclusion] Through multi-scale coupled analysis, the erosion mechanism of hydrogen pipelines has been elucidated, clarifying the influence of the interaction between medium physical properties and particle dynamics on erosion behavior. This research offers a theoretical reference for regulating flow velocity and impurity content in hydrogen stations, reducing the risk of elbow failure, and establishing a foundation for the reliability design and standard formulation of hydrogen energy infrastructure.
