多因素影响下掺氢天然气管道输运过程泄漏扩散的研究进展
Advances on leakage and diffusion of hydrogen-enriched natural gas pipeline transport under multiple influencing factors
摘要
Abstract
As countries worldwide accelerate efforts toward carbon peaking and carbon neutrality,hydrogen has emerged as a critical energy carrier in this transition.Transportation through hydrogen-enriched natural gas(HENG)pipelines is a vital approach to enabling large-scale,efficient,cost-effective,and safe hydrogen delivery.However,the potential risks associated with leakage and gas dispersion during pipeline transport remain a significant concern.Numerous scholars have conducted extensive research through experiments and numerical simulations to investigate the impacts of leakage orientation,pipeline pressure,orifice characteristics,ventilation conditions,and hydrogen blending ratio on the consequences of gas leakage.The influencing factors were categorized into three groups:leakage source characteristics,environmental conditions,and gas properties.A comprehensive review of how these factors individually or synergistically affect the risks and outcomes of leakage accidents was provided.Despite this progress,most existing studies rely heavily on numerical simulations with limited experimental validation.Therefore,it is essential to integrate experimental data,refine theoretical models,and develop high-accuracy gas dispersion prediction methods along with real-time monitoring technologies.关键词
