Fokker, Floris (author)In this thesis, the hydrodynamic limit (HDL) for two trapping models is studied, the Random Waiting Time Model (RWTM) and the fractional kinetics process (FKP), on a discrete lattice Zd . The RWTM is studied for dimension d ≥ 1 and E[wi ],∞where wi denotes the waiting time at position i . On the other hand, the FKP is studied for d ≥ 3 and a...bachelor thesis 2023

Schiereck, Arianne (author)Estuaries support a unique hydrodynamic system due to the fresh water flowing into a salt water sea. This leads to stratification which can significantly alter internal tidal dynamics in the estuary. A model has been developed by Winant (2010) to describe the water motions of a two-layer system in tidal basin. The aim of this thesis is provide...bachelor thesis 2020

Clarenburg, Jimmy (author)Designing a controlled offshore system is a challenging process, the system dynamics are often nonlinear and subjected to loads that are random in nature. Furthermore, the proper description of the system’s dynamical behaviour involves knowledge pertaining to several fields. Unfortunately, at the design level, the process is often segregated...master thesis 2019

Buckman, L.J. (author)Introduction: The addition of vegetation to the banks urban drainage channels is an increasingly common measure for improving water quality, enhancing ecological health, and improving aesthetic appeal. An in-stream wetland concept is proposed for channels in Singapore to just that, but faces a major challenge in that high flow rates during storm...master thesis 2013

Bodde, W.P. (author)Coral reefs are highly valuable structures in many respects and it is increasingly important to understand hydrodynamics and morphodynamics around reefs to be able to better protect them and their hinterland. Flume experiments were performed on a scaled fringing reef in the laboratory facilities of Deltares in Delft. The objective of this thesis...master thesis 2013

Benedysiuk, Piotr (author)Particle - particle interactions in graphene force charge carriers to behave as viscous liquid. In this report we model and study such a system in the framework of molecular dynamics. Two interaction regimes are studied, Dirac regime with negative interaction potential and Fermi regime with positive potential. We report on numerical stability...master thesis 2019

Leal Campos Fonseca da Silva, Renan (author)Spurs-and-grooves (SAG) are a common and impressive characteristic of shallow fore reef areas worldwide. Although the existence and geometrical properties of SAG are well-documented ever since the 50’s, the literature concerning specifically the hydrodynamics around them is sparse. This study provides a characterization of the 3D flow patterns...master thesis 2017

Pavilons, David (author)The most violent breaking waves cause the largest platform forces at sea, however it is unknown which wave in a sea state leads to these forces if run-up is included. Offshore inspection platforms give access to wind turbine monopiles. They are positioned above mean sea level. Wave interaction with monopiles leading to runup causes vertical...master thesis 2022

Veldhuizen, Jelmer (author)Hydraulic structures that are surrounded by flowing water can experience undesirable Flow-Induced Vibrations. These vibrations have a record of negative consequences. The most important cause of vibrations is self-excitation. This is a mechanism in which the forces acting on the hydraulic gate are amplified by the movement of the hydraulic gate...master thesis 2017

Guijt, Kamilla (author)The Eastern Scheldt basin is protected by a semi-open storm surge barrier that was completed in 1986. In 2015 a set of five turbines was installed in one of the barrier openings as a pilot for tidal energy extraction. Due to the construction of the barrier, the average tidal range and velocities have significantly decreased throughout the basin...master thesis 2018

Wiegman, Linda (author)Since the 1950s, numerical models are widely used in reservoir simulators to predict and optimize oil recovery from petroleum reservoirs. Commercial simulators typically combine multiphase porous media flow models with a separate module for the transport of tracers. By decoupling flow and transport, the transport equation can be solved using a...master thesis 2017

Te Wierik, M.H.J. (author)The first part of this thesis elaborates on two numerical models of different levels of comprehensiveness of a Laval rotor on plain journal bearings. These models are compared to an experiment, capable of rotating at 60 krpm, also devised in this research. Reasonable correlation in terms of whirl and whip behavior has been found. In the second...master thesis 2016

Parab Amit, V. (author)The use of azimuth thrusters as main propulsion device and for manoeuvring of ships is increasing over the past decades. However, the understanding of hydrodynamic loads acting on such devices in oblique inflow conditions is still an interesting area of research as it is generally believed that such loads can be partially responsible for the...master thesis 2015

Feenstra, Rinke (author)Allseas' Pioneering Spirit is the largest heavy lift vessel in the world. It uses its u-shaped bow to sail around an offshore platform and lift topsides up to 48.000t in a single lift. Despite being the largest vessel in the world, platforms exist that are simply too heavy, or too large to fit in between the bows of the vessel. Besides, smaller...master thesis 2018

Hendriks, A.J.H. (author)Objective Due the coastal protection program along the Dutch coast, the groins that first defended the coast against erosion, are now covered under sediment. Due to erosion the covered groins will resurface however. The objective of this study is to investigate the effect of the resurfacing groins on the hydrodynamics and sediment transport....master thesis 2011

van Tol, Berend (author)In this thesis, we study stochastic duality under hydrodynamic scaling in the context of interacting particles on a grid. The approach is inspired and motivated by the relation between duality and local equilibria. We identify duality relations in terms of the expectation of the density field for which the hydrodynamic limit is recovered. This...master thesis 2023

Liu, S. (author)This study is aiming to improve the understanding of hydrodynamic circulation in large shallow lakes. The Lake Taihu, the third largest lake in east China, is picked up as the study area for three reasons. The basin of Lake Taihu is considered as the most populated and developed area as a backyard of Shanghai. Lake Taihu is a typical shallow...master thesis 2013

SAXONI, IOANNA (author)Coastal regions are more and more affected by changes in water levels, storm patterns etc. owing to climate change. Nourishments and other human interventions constitute common practice in order to maintain and secure these areas. However, many aspects, especially the hydrodynamics, are not yet fully understood due to the complexity of the...master thesis 2018

Bos, M.F.M. (author)The wetlands in the Mississippi delta (USA) are drastically subsiding and eroding. Many projects and researches are ongoing to determine how this “drowning effect” of the delta can be stopped. One of the solutions that could be feasible is implementing sediment diversions in the levees of the Lower Mississippi River in order to divert sediment...master thesis 2011
