Abstract

Abstract:

The processes of LNG continuously leaking from pipeline and spreading were simulated by using the FLUENT software.The effect of pressure,different pipe leakage aperture and wind speed conditions on LNG continuous leakage and diffusion process were analyzed.The combustible explosive range and low temperature frostbite range expanding process with the LNG vaporous cloud spread were simulated and analyzed.The research results have reference value on LNG facility safety management.

Key words: natural gas, diffusion, numerical simulation

摘要：

利用FLUENT软件对LNG管线连续泄漏和扩散进行了模拟计算,分析了不同管内压力、泄漏孔径和环境风速条件对LNG连续泄漏及扩散过程的影响,分析气云随时间扩展过程中的燃烧爆炸范围和低温冻伤范围的变化。研究结果对LNG设施的安全管理具有参考意义。
