摘要:
主要利用FLACS软件,对水陆两处不同的界面下,LNG在同等气象条件下的扩散情况做了相关研究,利用FLACS软件前置处理器CASD对建立简单模型,拟定计算方案进行模拟仿真,对模拟结果进行整理分析后,得到水陆两个不同扩散层面液化天然气气液两相扩散结果与最大扩散距离。处理数据得到LNG气液两相扩散距离,对比结果可知LNG在水面蒸发速率大于地面蒸发速率且扩散距离远远大于地面扩散距离,可燃区域覆盖面更为宽广,说明水面扩散速率大于地面扩散速率。
Abstract:
The dispersion of LNG on water and ground under the same meteorology conditions was studied by using FLACS software. The preprocessor CASD was applied to create a simple model, and a calculation scheme was made to conduct the simulation. After collating and analyzing the simulation results, some conclusions of LNG dispersion on water and ground were obtained. By the comparison of these two conditions, the distances of LNG's twophase diffusion were obtained. It showed that the evaporation rate of LNG dispersion on the water is faster than that on the ground, and the combustible region on the water is wider than that on the ground. These indicate that the diffusion rate on the water is faster than that on the ground.
