燃气管道非等温非稳态泄漏模型

Nonisothermal and Unsteady State Leakage Model for Gas Pipelines

    摘要
  • 摘要: 估算燃气管道的泄漏率和泄漏压力, 对分析和预测燃气泄漏事故的损失十分重要。通过对现有气体泄漏率计算模型的研究, 应用计算流体力学理论, 推导了燃气管道非等温非稳态泄漏率的计算方法。实例分析表明, 当燃气管道泄漏口径较大或断裂时, 该数学模型可以精确地计算气体的泄漏率。

     

    Abstract: Estimating leakage volume ratio and leakage pressure is very important to analyze and predict economic loss of gas leakage accident for gas.Based on research on current mathematical model of gas leakage ratio, calculation method of nonisothermal and unsteady state leakage ratio for gas pipeline is deduced.Case analysis results show that leakage ratio for gas can be accurately calculated by means of the mathematical model when diameter of leakage opening is big or pipe is broken.
