NUMERICAL SIMULATION OF THE BOTTOM DISCHARGE PROCESS OF A TRAILING SUCTION HOPPER DREDGE

Suspended pipeflow with openfoam

In dredging applications, deep sea mining and land reclamation projects typically large amounts of sediments are transported through pipes in the form of hyper concentrated (40% sediment or more) sediment-water mixtures or slurry. These slurries can flow at three different regimes. 1: fully suspended (homogeneous and stratified) 2: partially...

Two-phase modelling for sediment water mixtures above the limit deposit velocity in horizontal pipelines

In dredging applications, deep sea mining and land reclamation projects typically large amounts of sediments are transported through pipes in the form of hyper concentrated (40% sediment or more) sediment-water mixtures or slurries. In this paper it is investigated how well a generic Euler-Euler CFD-model is capable to model velocity,...
