Keetels, G.H. (author), Chauchat, Julien (author), Breugem, W.P. (author)Reliable prediction of the erosion rate of sediment beds is important for many applications in coastal and river engineering. Theoretical understanding of empirically derived scaling relations is still lacking. This applies in particular for the scaling anomaly between low and high Shields number conditions. In this work, the erosion process is...journal article 2023

Bolhuis, Thirza (author)Layman Summary<br/>The goal of this paper is to study how waves move over a fluid in with an underlying current. Oceans displace debris and heat. Ocean models can be used to predict the movement of debris and even predict the effect of the movements of oceans on the climate. Modeling water can be improved by introducing more information from...bachelor thesis 2022

Geyer, A. (author), Quirchmayr, Ronald (author)We develop a Korteweg-De Vries (KdV) theory for weakly nonlinear waves in discontinuously stratified two-layer fluids with a generally prescribed rotational steady current. With the help of a classical asymptotic power series approach, these models are directly derived from the divergence-free incompressible Euler equations for unidirectional...journal article 2022

Li, Xuebo (author), Hutchins, Nicholas (author), Zheng, Xiaojing (author), Marusic, Ivan (author), Baars, W.J. (author)A large-scale spanwise and wall-normal array of sonic anemometers in the atmospheric surface layer is used to acquire all three components of instantaneous fluctuating velocity as well as temperature in a range of stability conditions. These data permit investigation of the three-dimensional statistical structure of turbulence structures....journal article 2022

Soares, Ana (author), Camargo, Juliano (author), Al-Koussa, Jad (author), Diriken, Jan (author), Van Bael, Johan (author), Lago, Jesus (author)Estimating the state thermal storage devices is key to use them efficiently to reduce the uncertainty of renewable sources. Although stratified storage tanks are one of the most efficient and cost-effective storage systems, they lack accurate state estimation methods. In this paper, we propose a general methodology for estimating the state of...journal article 2022

Jakšić, Luka (author)In times of rapid urbanization, engineering interventions in coastal systems have become more common. It is important to understand the interplay of these engineered solutions with their natural environment to minimize hazardous side effects to our ecology, economy and coastal safety. In a numerical study by Rijnsburger (2021), a flow...master thesis 2021

Gopalan Jayashankar, Gopalan (author)Multiphase flows are very common in many Nuclear engineering applications. During high pressurized conditions there are possibilities of high thermal loads on the pressure vessel, leading to pipe ruptures. As part of breakdown measures, the emergency core cooling system is activated and the coolant is mixed with the fluid in the cold leg, giving...master thesis 2021

ten Harmsen van der Beek, Noor (author)Salt intrusion poses a threat to the fresh water supply function of inland waterways. How far inland salt intrusion reaches is dependent on a balance of buoyancy forcing, water depth, discharge of the canal and the amount of mixing. Wind, bottom roughness, and sailing ships contribute to mixing. Currently, little is known about the contribution...master thesis 2021

Wegman, Tess (author)Due to climate change and human interventions, saltwater intrusion is becoming a topic of increasing concern worldwide. Salt water intrudes into the Rotterdam Waterway (RWW) by an exchange flow, where the denser sea water propagates landwards at the bottom. The main competing mechanism for this stratified exchange flow is...master thesis 2021

Tempel, Auke (author)Regular maintainance dredging is a large expense to the Port of Rotterdam, therefore the installation of sediment traps is considered. By increasing the bathymetry locally, an increase of local accumulation is expected and a decrease deeper in the harbour basin. This thesis describes the functioning of sediment traps in a stratified tidally...master thesis 2019

Lago, Jesus (author), De Ridder, Fjo (author), Mazairac, Wiet (author), De Schutter, B.H.K. (author)To mitigate the effects of the intermittent generation of renewable energy sources, reliable and efficient energy storage is critical. Since nearly 80% of households energy consumption is destined to water and space heating, thermal energy storage is particularly important. In this context, we propose and validate a new model for one of the...journal article 2019

Messaadi, M. (author), Steenbergen, M.J.M.M. (author)This study examines the properties of stratified surface layers on rails in service and presents a hypothesis explaining their origin. The stratified layer consists of a white etching top layer and a brown sublayer. The metallurgical composition and properties of this sublayer are found to match with that of globular bainite. The occurrence...journal article 2018

Hazari, S.A. (author)Stratified two phase flow is one of the flow regimes that is of importance in multiphase flow transport through pipelines, such as used for example in the oil and gas industry. Its application also extends to chemical production, energy conversion and food processing. The phenomenon of turbulence further complicates the stratified flow behaviour...master thesis 2016

Birvalski, M. (author), Tummers, M.J. (author), Henkes, R.A.W.M. (author)An experimental study was performed in stratified wavy flow of air and water through a horizontal pipe. The velocity fields in both phases were measured simultaneously using PIV and the interfacial shape was resolved using a profile capturing technique. The objective of the study was to investigate the interfacial characteristics and the...journal article 2016

Commandeur, A.S. (author)Turbidity currents are major transport agents in reservoirs in which high concentrations of fine sediments flow in. Reservoir sedimentation due to turbidity currents is often severe in these cases. Turbidity currents are not well understood due to their complex turbulent flow structure, the interaction between the flow with the particles and the...master thesis 2015

Birvalski, M. (author)The growing demand for energy in the future will necessitate the production of natural gas from fields which are located farther offshore, in deep water and in very cold environments. This will confront us with difficulties in ensuring continuous production of the fluids (natural gas, condensate and water) emerging from a natural gas well. Often...doctoral thesis 2015

De Jong, M.D. (author)This thesis describes FPGA-accelerated Monte-Carlo integration using adaptive stratified sampling. Monte-Carlo integration can be used to determine the value of integrals that have no closed form solution. In this work, the FPGA-accelerated design is used to determine the price of different types of financial options. The considered options are...master thesis 2014
