地下综合管廊管道泄漏扩散的研究进展
|
摘要
地下综合管廊管道泄漏扩散引起的突发事故,往往造成重大损失和社会影响,针对国内外地下综合管廊管道泄漏扩散问题,从实验研究、理论分析及数值模拟3方面对其研究现状进行了归纳分析。在实验方面以典型实验方法为依据,分析了现有实验存在的问题;在理论分析方面建立了不同介质泄漏的数学模型,用其确定关键物理参数;在数值模拟方面主要对单源泄漏扩散进行研究,一般均为二维模拟计算。此外还结合研究现状总结了一些地下综合管廊管道泄漏扩散的规律。在以后的研究中不仅应该侧重于多源泄漏扩散的三维数值模拟计算,而且需要根据实际工况开展一些典型的验证实验,不断对理论分析模型进行合理修正。
Sudden accidents caused by the proliferation of pipeline leaks in underground comprehensive pipelines often result in heavy losses and social impacts.This article addresses the problems of pipeline leakage diffusion at home and abroad from experimental research,theoretical analysis and numerical simulation.In the experimental aspect,based on the typical experimental methods,the existing problems in the existing experiments were analyzed.In the theoretical analysis,the mathematical models of different media leakages were established,and the key physical parameters were determined.In the numerical simulation,the single source leakage diffusion was mainly performed.Studies are generally two-dimensional simulations.In addition,combined with the research status,the rules of the leakage and diffusion of some underground comprehensive pipe corridors are summarized.In the future research,we should not only focus on the three-dimensional numerical simulation of multi-source leakage diffusion,but also need to carry out some typical verification tests based on the actual working conditions and continue to rationally correct the theoretical analysis model.
