- 摘要:
- 为了评价在开阔水面上的液化天然气（LNG）火灾和蒸气云爆炸灾害后果，分析了LNG水面扩展动态过程；对比分析了Fay模型、FERC模型和计算流体力学软件FLACS的计算结果，探讨了LNG液池面积随时间的动态变化过程，分析了泄漏量、泄漏速率等参数对LNG液池扩展半径的影响；根据液池扩展模型的计算结果，确定了LNG液池的最大面积，并以此分析了LNG流淌火灾的辐射危害。研究结果表明：对于相同的泄漏条件，3种方法模拟的泄漏LNG水面扩展动态过程相似，一般情况下，FLACS模型，FERC模型和Fay模型所计算的最大液池半径依次增大;由于FERC模型与FLACS软件的模拟结果接近且偏于保守，故此在一般的工程应用时，采用FERC模型即可方便快捷地获得较为准确的结果。
- Abstract:
- In order to evaluate the consequence of fire and vapor cloud explosion for the liquefied natural gas (LNG) on the open water surface, the dynamic process of LNG spreading on the water surface was analyzed. The comparative analysis on the calculation results of Fay method, Federal Energy Regulatory Commission's (FERC) model and FLACS, a computational fluid dynamics (CFD) software was carried out, then the dynamic changing processes of LNG liquid pool area with time were discussed, and the influence of the leakage amount, the leakage rate and other parameters on the spread radius of LNG liquid pool was analyzed. According to the calculation results of the liquid pool spread model, the maximum area of LNG liquid pool was determined, and the thermal radiation hazard of LNG flowing fire was analyzed on this basis. The results showed that under the same leakage conditions, the dynamic processes of LNG spreading on the water surface simulated by the three methods were similar. Generally, the maximum liquid pool radius calculated by the FLACS, FERC model and Fay model increased in turn. The simulation results of FERC model were close to that of FLACS and more conservative, so the more accurate results could be obtained conveniently and rapidly by using FERC model in the general engineering application.
