文摘

The dynamic behaviour of catenary pipelines subjected to internal slug-flow is investigated. The two phase flow model is assumed to be steady. The pipeline dynamics are investigated in the two dimensional space. The system of differential equations is generic and accounts for the steady effect of the internal liquid as is conveyed through the structure.
