摘要
随着民航行业的快速发展,广泛使用管道运输喷气燃料.但是管道中的水分容易在低洼处聚积,并带来腐蚀和流动不畅等一系列问题.基于计算流体力学(CFD)方法对不同倾角上倾管道中喷气燃料携带底部积水情况进行了计算机仿真.计算结果表明,随着时间的增加,在喷气燃料的剪切作用下,管底积水将被分成大水团和小水滴两部分;随着倾角的增大,大水团的轴向长度变短,相界面波动剧烈,导致管底水相出现回流现象进而流动速度变缓.
Abstract
With the rapid development of civil aviation industry,pipelines are widely used for transportation of jet fuel.However,the water in the pipeline is easy to accumulate in low-lyubg areas,leading to a series of problems such as corrosion and poor flow.A computer simulation was conducted based on the Computational Fluid Dynamics(CFD)method to investigate the bottom water accumulation carried by jet fuel in upward inclined pipelines with different in-clination angles.The results show that with the increase of time,the accumulated water at the bottom of the pipe will be divided into large water masses and small water droplets under the shear action of jet fuel;With the increase of in-clination angle,the axial length of large water masses becomes shorter and the interface becomes more intense,resul-ting in backflow of water phase,and then the flow velocity becomes slower.
