摘要:
采用经典流体力学理论，以及计算流体力学（CFD）等方法相结合，对中缅油气 管线上具有代表性的岩鹰山隧道进行研究。用Fluent软件对岩鹰山隧道天然气管道泄漏 进行仿真模拟，利用Fluent模拟结果与泄漏源计算结果相结合，经过理论分析与数据拟 合，提出泄漏天然气充满隧道的时间计算模型，通过不同边界条件下隧道内天然气泄漏 扩散规律的模拟结果对时间模型进行验算并修正。利用计算流体力学（CFD）方法，研 究岩鹰山隧道在发生天然气泄漏事故后，单风机通风方案的效率，得出隧道通风优化方 案，方案内容包括最佳送风方式、布设水平位置、布设高度、布设间距。根据通风方案 计算结果对风机型号选取、以及隧道洞门设计提出了建议。
Abstract:
The classical fluid dynamics theory and computational fluid dynamics (CFD) method were combined to study the most representative Yanyingshan tunnel of the Sino-Burma Oil & Gas Pipeline. The leakage of natural gas pipeline in Yanyingshan tunnel was simulated by using Fluent software, and combined the simulation results by Fluent with the calculation results of leakage source, a calculation model on time to fill the tunnel by leaking natural gas was put forward through theoretical analysis and data fitting. The time model was checked and corrected through the simulation results of gas leakage and diffusion in the tunnel under different boundary conditions. The efficiency of single fan ventilation scheme during the accident of gas leakage in Yanyingshan tunnel was studied by using CFD method, and the optimization scheme of tunnel ventilation was obtained, which included the optimal air supply mode, layout horizontal position, layout height and layout spacing. The suggestions on fan model selection and tunnel portal design were proposed according to the calculation results of ventilation scheme.
