Sarıgöl, Barkin (author)Various potential flow methods with different assumptions are available to quantify the efficiency increase and thrust provided by a swirl recovery vane (SRV). In this paper, thrust coefficients and efficiency results obtained by different potential flow methods for the same SRV geometry at different advance ratios are presented. The methods...student report 2023

Kislaya, A. (author)The precise manipulation of particles and droplets is crucial to many microfluidic applications in engineering. The design of microfluidic devices is generally tailored to perform a specific task, with each specific application requiring a unique and fixed design. In this way, using a single device to perform multiple analyses of a wide range of...doctoral thesis 2022

Borren, Marc (author)While the awareness of global warming rises, transport over sea remains a large contributor to green house gas emissions. New regulations imposed by the International Maritime Organization (IMO) aim to reduce the emission of green house gasses. Consequently, ship owners turn to technological solutions in order to achieve this. The Ventifoil from...master thesis 2022

Ferschtman, Josef (author)In the modern world, environmental concerns arise due to an increase in the green house gas (GHG) emissions of the shipping industry; in 2015, 2,5% of global GHG emissions came from the shipping industry alone. Measures must be set in place to reduce the future emissions. One way to reduce emissions is by imposing the Energy Efficiency Design...master thesis 2022

van Hoof, Sjoerd (author)At the moment, the world is at the verge of an energy transition. One of the most promising green resources is solar energy, which is a rapidly growing market. However, to fully use its potential of economy of scale, the application of offshore floating solar should be explored. A promising option is the use of a flexible type of Very Large...master thesis 2021

van Essen, S.M. (author), Monroy, Charles (author), Shen, Zhirong (author), Helder, Joop (author), Kim, Dae Hyun (author), Seng, Sopheak (author), Ge, Zhongfu (author)Design loads for extreme wave events on ships, such as slamming and green water, are hard to define. These events depend on details in the incoming waves, ship motions and structure layout, which requires high-fidelity tools such as CFD or experiments to obtain the correct loads. These tools (presently) do not have the capability to fully...journal article 2021

Hendrix, Emile (author)Ventilation events are the result of masses of air being transported from the water surface along the hull, through the propeller plane. Previous research in literature has shown that ventilation induces large and sudden variations of the load on the propeller. The response of the propulsion system had not been documented before. This is a...master thesis 2020

Bots, Michiel (author)Floating offshore wind turbines can only withstand a limited amount of (heave) motions before the equipment fails. In order to reduce the heave motion, the DeepCwind floater for offshore floating wind turbines makes use of heave plates. This semi-submersible floater consists of three cylindrical columns with a heave plate attached to the bottom...master thesis 2020

Bussemakers, P.J.M. (author)Climate change, as a result from global warming, requires an energy transition: the reduction of greenhouse gas emissions from fossil fuels and a radical innovation of the global energy system to proceed apace. Offshore wind is an important source of clean, renewable energy, and it plays a key role in the transition. 80% of the worldwide...master thesis 2020

Akkerman, I. (author), Meijer, J. H.A. (author), ten Eikelder, M.F.P. (author)This paper presents a novel variational formulation to simulate linear free-surface flow. The variational formulation is suitable for higher-order finite elements and higher-order and higher-continuity shape functions as employed in Isogeometric Analysis (IGA). The novel formulation combines the interior and free-surface problems in one...journal article 2020

Each OWC chamber is enclosed by two partially submerged vertical walls and the deck of the platform. An incident wave produces oscillation of the water column in each OWC chamber and hence air...journal article 2020
