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...

Soft mud deposits are increasingly encountered around the world, from natural offshore deposits and mud layers in estuaries, ports, and waterways to progressively growing leftover from treatment and extraction facilities, mines, and oil refineries. Reliable monitoring of the temporal and spatial strength buildup in such deposits is crucial to...

The hydraulic transport of sediments in sediment–water multiphase mixtures is an important process in nature and many industrial applications. The flows are characterized by complex transient phenomena, in which the overall system scale and the particle scale are equally important. Experimental research into dense mixture flows is focused on...

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...

This paper presents an improvement on a previous model for predicting the Marsh funnel (MF) test that is used in slurry shield tunneling for evaluating the rheological properties of bentonite slurries. The improvement focuses on the prediction of the dynamic part for fluids with small MF times. The velocity profile of the Herschel-Bulkley...

Natural mud sediments display complex rheological behaviour like thixotropy, viscoelasticity and yield stress. These rheological characteristics can significantly vary over depth, from one mud layer to another, as each layer can have a different density and composition. Fast and reliable measurements of yield stresses of mud samples are...

The mining of polymetallic nodules from the seafloor at depths down to 6000m requires the excavation of nodules with a seafloor mining tool, the transport of nodules as a slurry through a jumper hose connecting the mining tool to a vertical hydraulic transport system and the transport of the nodules through the vertical lifting pipe. We focus...

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...

A bend or any another pipe component disturbs solids transport in pipes. Longitudinal pressure profiles downstream of such a component may show a stationary transient harmonic wave, as revealed by a recent settling slurry laboratory experiment. Therefore the fundamental transient response of the two-layer model for fully stratified flow is...

The stagnation pressure at a certain distance from the nozzle is important for the erosion/ cutting capacity of a submerged jet in dredging. The decay of the stagnation pressure with jet distance is well known in the case of non-cavitating jets. It is also known that cavitation causes the rate of decay to decrease. Under conditions of cavitation...

Er wordt een eenvoudige methode gegeven om vanuit de groutinjectieverdeling en de grouteigenschappen, de verticale groutdrukgradiënt direct achter de TBM te kwantificeren. Deze groutdrukgradiënt is nodig als input voor de berekening van het krachtenspel in de tunnelbuis tijdens tunnelbouw. Het bestaande gefaseerde analytische liggerwerkingsmodel...

Flow equations for application in river bends are derived. Coordinate transformations are achieved by tensor calculus. The momentum equations are formulated in a cylindrical coordinate system and in a cylindrical bed-following coordinate system. The depth-averaged momentum equations in a cylindrical bed-following coordinate system are derived....

Bed-levelling experiments are conducted in a straight laboratory channel. The experiments involve a significant fraction of suspended sediment transport. The purpose of the experiments is to provide data for modelling of the direction of sediment transport on a transverse sloping alluvial river bed, specifically in presence of suspended sediment...

A suspended sediment transport experiment in a straight flume with a mobile bed is reported. The bed topography is non-horizontal. The flow is steady. Due to an obstruction in the entrance a steady bed oscillation is generated. The bed topography is measured by means of manual bed soundings (by Delft Hydraulics). Suspended sediment...

A laboratory experiment in a 180 degree curved flume with a mobile bed and suspended sediment transport is reported. The flow is steady. The bed topography is measured by means of a profile indicator. Free and forced alternating bars are present. The steady part of the bed topography, which is forced by curvature, is characterized by a below...
