湿度对天然气扩散影响的理论分析

摘要

近年来，对天然气管道及泄漏过程的研究大多数都集中在风速、障碍物和温度对于污染物的扩散影响，往往忽略了气象条件的作用，尤其是大气湿度变化对扩散的影响。而实际观测结果能够体现大气湿度变化对于气体污染物和颗粒污染物扩散的具体影响，却没有理论模型的支持。从气体扩散理论出发，研究了湿空气下的天然气扩散，以菲克理论进行理论分析，重点提出了气体扩散的影响因素。%In recent years,most studies of gas pipelines and the leak process have focused on the influence of diffusion for pollutants in wind speed, obstacles and temperature , often neglected the role of meteorological conditions, especially the effects of changes in atmospheric humidity for diffusion. But the actual observation results can reflect the atmospheric humidity changes for specific effects of diffusion of gaseous pollutants and particulate pollutants, there is no theoreticalmodel to support. From the gas diffusion theory to study gas diffusion on the wet air, to Fick theory analysis, puts forward the influencing factors of gas diffusion.
