Shear settling in laminar open channel flow: analytical solution, measurements and numerical simulation

In beaching of tailings, sand and clays may segregate. In laminar flow this is due to shear settling. First implementations of shear settling in numerical flow models are seen, offering unprecedented potential to conduct tailings management studies. In order to validate numerical codes, reference materials are necessary. For laminar flow, there...

Towards improving predictions of non-Newtonian settling slurries with Delft3D: theoretical development and validation in 1DV

To date there is limited knowledge about the flow behaviour of non-Newtonian slurry and tailings flows. In hydraulic engineering and the mining industry numerous questions and uncertainties still exist. Different numerical and analytical models have been developed attempting to meet this demand. For the larger part they describe the rheological...

Deposition of high density tailings on beaches

One of the biggest uncertainties affecting the operations of mine and land reclamation activities is related to tailings / slurry management, for which the processes of beach deposition play a critical role. Deposited tailings produce both sheet and channelised flow, causing varying velocity profiles which lead to differential settlement. This...
