| 摘 要： | 管道中不满流动状态的存在对管道的正常运行和停输产生较大影响,容易引起管道事故.因此,对地形起伏管道翻越高峰点后的流动特点进行了分析,根据流体力学连续性方程和动量方程建立了不满流动的数学模型,并结合现场数据进行了投产时期水隔离段的不满流动截面参数计算；通过分析计算结果可知,影响不满流段气体含量的因素包括管道坡度、流体流量...

| Abstract: | The presence of underfilled flow in a pipeline greatly affects the normal operation and shutdown of it and will probably cause accidents.The features of flow in pipelines in hilly areas after they climb a peak point are analyzed,and a mathematic model for the underfillied flow is formed,based on a discontinuity equation and a momentum equation in light of fluid mechanics.Combined with the field data,parameters of the underfilled flow within a water-isolated section are calculated during the commission perio... |
