摘要:
为研究二氧化碳管道在复杂地形及建筑条件下的扩散特性，确定CO2管道泄漏扩散后导致的潜在危害区域，采用有限元方法，以k-ω SST模型为基础，构建典型场景下的管道三维模型，分析建筑物类型、地形条件、泄漏孔径对CO2泄漏扩散变化的影响，根据数值分析结果构建平坦地形下泄漏影响范围的多元回归方程。研究结果表明：CO2泄漏距离受到建筑物、风速及泄漏孔径的影响。研究结果可为平坦地形泄漏及地形起伏较大且外部环境复杂的二氧化碳管道泄漏危害区域提供理论支撑。
Abstract:
To investigate the diffusion characteristics of CO2 pipelines under complex terrain and building conditions,and determine the potential hazardous areas caused by CO2 pipeline leakage and diffusion,a three-dimensional model of the pipeline under typical scenes was constructed based on the k-ω SST model by using the finite element method.The influence of building types,terrain conditions,and leakage hole diameters on the change in CO2 leakage and diffusion was analyzed,and the multivariate regression equations for the influence range of leakage under flat terrain were developed according to the numerical analysis results.The results show that the CO2 leakage distance is influenced by the building,wind speed,and leakage hole diameter.The research results can provide theoretical support for assessing the hazardous areas of CO2 pipeline leakage in flat terrain as well as in areas with significant topographical variation and complex external environments.
