采用流体力学软件Fluent对不同风速下管道天然气泄漏扩散过程进行了数值模拟,获得了计算区域内天然气泄漏随风速变化的扩散规律。结果表明较大的风速可以使天然气向下风向更远的距离扩散,从而增加了天然气爆炸的危险浓度的范围。
The fluid dynamics software Fluent was used to simulate the natural gas leakage and diffusion processes at different wind speeds. The diffusion rules of natural gas leakage with wind speed were obtained. The results show that larger wind speeds can spread natural gas to a greater extent in the downwind direction, increasing the range of dangerous concentrations of natural gas explosions.
