Ali, W. (author)Deep-sea mining Industry and academia are presently investigating the potential of deep-seamining for valuable resources such as poly-metallic nodules. Nevertheless, the process of manoeuvring, excavating, and processing these resources poses a threat to the deep-sea environment through the generation of plumes of suspended fine-grained solids,...doctoral thesis 2024

Alkemade, Anne-May (author)<br/>In response to the sharp decline of seagrass globally, various restoration techniques have been developed and applied; many at limited scale and with limited success. This research focuses on the fluid mechanics and behaviour of seagrass seeds in a sand mixture through physical laboratory experiments. The objective is to establish a...master thesis 2024

(author)Particle tracers are sometimes used to track sources and sinks of riverine particulate and contaminant transport. A potentially new particle tracer is ~200 nm sized superparamagnetic silica encapsulated DNA (SiDNAFe). The main objective of this research was to understand and quantify the settling and aggregation behaviour of SiDNAFe in river...journal article 2023

Zomerdijk, M.J.J. (author), van der Wijk, V. (author)Industrial robotic manipulators in pick-and-place applications require short settling times to achieve high productivity. The fluctuating reaction forces and moments on the base of a dynamically unbalanced manipulator, however, cause base vibrations, leading to increased settling times. These base vibrations can be eliminated with dynamic...journal article 2022

Zhou, Z. (author), Ge, Jianzhong (author), van Maren, D.S. (author), Gu, Jinghua (author), Ding, Pingxing (author), Wang, Zhengbing (author)The Krone–Partheniades (K-P) framework has been used for decades to quantify and analyze the sediment exchange at a water–bed interface. Measuring the erosion and deposition parameters that are part of this framework requires time-consuming field observations. Additionally, the erosion parameters are measured independently of deposition...journal article 2022

(author), Spychala, Yvonne T. (author)A revision of the popular equation of Richardson and Zaki (1954a, Transactions of the Institute of Chemical Engineering, 32, 35–53) for the hindered settling of suspensions of non-cohesive particles in fluids is proposed, based on 548 data sets from a broad range of scientific disciplines. The new hindered settling equation enables...journal article 2022

Huang, Ziyang (author)To meet energy demand towards a low-carbon future, the global market demand is growing for metals such as cobalt and nickel which are major elements in batteries. Polymetallic nodules, which are formed on abyssal plains at depths ranging from 4 to 6 kilometres and are distributed in high abundance on the top of the seabed, contains several times...master thesis 2021

Kramer, O.J.I. (author)In drinking water treatment plants, multiphase flows are a frequent phenomenon. Examples of such flows are pellet-softening and filter backwashing where liquid-solid fluidisation is applied. A better grasp of these fluidisation processes is needed to be able to determine optimal hydraulic states. In this research, models were developed, and...doctoral thesis 2021

Enthoven, dolf (author)Due to the increased demand for materials like cobalt and nickel, there is an interest to mine polymetallic nodules from the deep-sea. These nodules are abundantly distributed along the abyssal plains, e.g., the Clarion Clipperton Zone (CCZ) in the North East Pacific. These nodules lay spread on top of a seabed consisting of very fine clayey...master thesis 2021

Liu, Jordi (author)Within a Protoplanetary disk (PPD), planets form from micron sized particles, but what are the processes taken for planet formation? How does the evolution of micron sized particles via settlement and coagulation lead to the gigantic planets as the ones in our Solar System? This thesis explores the planet formation process of pebble accretion...master thesis 2021

Shakeel, A. (author), Kirichek, Alex (author), Chassagne, C. (author)Kaolinite suspensions are known to have quite fast settling behaviour and Newtonian character, particularly at low concentrations, due to the non-swelling nature of their constitutive particles. On the other hand, bentonite is known for its swelling and interacting nature, which leads to the formation of a network structure, even at low...journal article 2021

Veenman, Tjerk (author)In this study, the behaviour of fine sediment in settlings basins has been investigated. The understanding and prediction of return water quality assessments is improved by a comparative modelling study. Settling basins are required to decrease the exhaust of fine sediment particles when dredging and reclaiming land. Fine sediment particles can...master thesis 2020

Nering Bögel, Meyke (author)In 2018, the number of forcibly displaced people all over the world was higher than ever before. More than a third of this group are refugees, often living in refugee camps. NGOs try to deliver all necessary aid to these camps, while facing limited access and resources. Therefore, they want to optimize the results of the aid they deliver. The...master thesis 2020

A wide range of clay concentrations was used, i.e., from 0.07 to 1000 g/L for different experimental techniques, based on the fact that the clay...journal article 2020

van Dijk, E.J.H. (author), Pronk, M. (author), van Loosdrecht, Mark C.M. (author)The settling behavior of aerobic granular sludge (AGS) in full-scale reactors is different from the settling of normal activated sludge. Current activated sludge models lack the features to describe the segregation of granules based on size during the settling process. This segregation plays an important role in the granulation process and...journal article 2020

Kirov, Nikolay (author)Surprisingly, liquid media of dispersed dry micron-sized particles can generate tremendous impact resistance, can grow solid protrusions when acoustically-vibrated and can cause a range of other peculiar phenomena to objects sinking in their interior, even though their appearance essentially remains ’liquid-like’. These heterogeneous mixtures of...master thesis 2019

(author)One of the most popular and frequently used models for describing homogeneous liquid-solid fluidised suspensions is the model developed by Richardson & Zaki in 1954. The superficial fluid velocity and terminal settling velocity together with an index makes it possible to determine the fluid porosity in a straightforward way. The reference...journal article 2019
