Transient Hydraulic Transport in Pipelines: On flow assurance influenced by slurry dynamics

Hydraulic transport pipelines are used in dredging, (wet) mining and deep sea mining. These pump-pipeline systems are typically designed using steady-state principles. However, recent cases have shown that steady-state design does not always guarantee stable pipelines. Transients like self-amplifying density waves have shown to be able to...

A 1-dimensional-two-layer transient drift-flux model for hydraulic transport pipelines: modelling and experiments of bed layer erosion and density wave amplification

Hydraulic transport pipelines in the dredging, mining and deep sea mining are designed using steady-state methods. However, these methods cannot predict density wave formation. Density waves form a risk for pipeline blockages, therefore there is a need to understand and preferably be able to model the process. The density waves studied in...

Predicting density wave amplification of settling slurries using a 1D Driftux model

Density wave amplification in hydraulic transport pipelines forms a high risk to operational continuity, as density waves can lead to system blockages or centrifugal pump drive failures. Recent experimental research, in pipelines which contain long vertical sections, has shown that density waves can amplify at velocities far exceeding the...
