| 摘 要： | 结合SLAB稳态烟羽模型,针对液化天然气(LNG)连续泄漏、水平喷射源的重气扩散过程进行了模拟研究,分析了液化天然气泄漏后混合云团扩散形成的浓度场、温度场和其它特征参数。利用MATLAB语言编制液化天然气连续泄漏扩散模拟程序,对两种试验环境条件(不同风速、大气温度、大气稳定度、相对湿度和地表粗糙度等环境参数)下扩散云团的特性参数进行模拟计算,得到各云团参数随下风向距离的变化规律。 |
| 关 键 词： | 液化天然气 连续泄漏 水平喷射源 重气扩散 SLAB模型 |

| Abstract: | Horizontal jet continuous release was studied through SLAB steady plume dispersion model.The concentration field,temperature field and other characteristics were calculated and analyzed.A MATLAB based program was developed to simulate the continuous leakage diffusion.The characteristics of the diffusion cloud under two different environment conditions were calculated.The environmental conditions included different wind speeds,temperatures,atmospheric stabilities,relative humanities and surface roughness.Changing trends of the diffusion clouds were predicted. |
| Keywords: | LNG continuous leakage horizontal jet release heavy gas diffusion SLAB model |
