| 摘 要： | 在分析清管物理模型的基础上,建立了清管器前段塞流动的特征参数计算模型、动态数学模型以及相应的数值计算方法,并进行了数值模拟。利用数学模拟方法可以计算清管过程中管线的压力分布,利用压力分布可以跟踪清管球在管线内的运行,这为混输管路的运行管理提供了理论依据。

| Abstract: | Pigging is a very important operation for pipeline.The pigging physical model was analyzed,and the mathematic models for expressing characteristic parameters of slug flow of pig,the dynamic model and numerical calculation method were developed.A computer-based data acquisition system was used to obtain the information of flow behaviors during experimental process.The changes of pressure with time and the pressure profiles at different periods of time along the pipelines were evaluated and compared fairy well with the experimental data.It shows that the pig in the pipeline has a significant affect on the operation parameters. |
