- 摘要:
- 随着中国天然气管网规模的扩大及纯氢/掺氢天然气管道输送需求的增长,管道摩擦阻力导致的输送效率下降问题日益突出。回顾了近年来输气管道减阻增输技术的研究进展,重点分析了内涂层技术与减阻剂技术的应用现状、机理及局限性。内涂层技术适用管径受限、施工复杂且难以修复的工况;减阻剂技术具有灵活经济的特点,但分子结构优化、机理研究及现场验证仍需突破。此外,沟槽和自适应表面等非光滑表面减阻技术通过改变近壁流动特性展现出发展潜力,但机理尚未统一。研究发现现有输气管道减阻增输技术普遍面临机理不完善、评价方法局限等问题。未来需结合多学科深化减阻机理研究,优化材料与工艺,提高输气管道的输送能力,助力“双碳”目标下清洁能源的高效输送。
With the expansion of China's natural gas pipeline network and the increasing demand for pure hydrogen and hydrogen-blended natural gas transportation, the decline in transmission efficiency caused by pipeline frictional resistance has become increasingly prominent. This paper reviews recent research progress on drag reduction and throughput enhancement technologies for gas pipelines, focusing primarily on the application status, mechanisms, and limitations of internal coatings and drag reduction agents. Internal coatings technology are constrained by pipe diameter limitations, complex construction processes, and difficulties in repair; drag reduction agent technologies offer flexibility and cost-effectiveness but still require breakthroughs in molecular structure optimization, mechanism elucidation, and field validation. Additionally, non-smooth surface drag reduction techniques—such as grooves and adaptive surfaces—show potential by modifying near-wall flow characteristics, although their mechanisms remain inconclusive. The study finds that existing drag reduction and throughput enhancement technologies generally face challenges including incomplete mechanistic understanding and limited evaluation methods. Future research should adopt multidisciplinary approaches to deepen the understanding of drag reduction mechanisms, optimize materials and processes, improve pipeline transmission capacity, and facilitate efficient clean energy transportation in support of China's “dual carbon” goals.
