Freitas, André (author)In the evolving landscape of nuclear energy, ensuring the safety and efficiency of nuclear reactors remains paramount, particularly with the increasing demands for energy and a concurrent rise in global temperatures. A significant aspect of nuclear safety involves maintaining the integrity of the fuel rods, which are susceptible to Turbulence...master thesis 2023

Koens, Dennis (author)High-tech systems are subjected to strict temperature requirements. Therefore temperature control using cooling water is vital for thermal stability. Unfortunately, components like pumps and fluid couplings generate flow disturbances, resulting in mechanical vibrations that influence the performance of the system. This research focusses on the...master thesis 2023

Formidabile, Martina (author)TOP contoured nozzles, with large area-ratios, are commonly employed in rocket propulsion systems as they feature an excellent thrust-to-weight ratio. A significant shortcoming to this design is that, during the startup and shutdown transients of a LRE, the internal nozzle flow progresses through a series of overexpanded flow states - Free Shock...master thesis 2023

Tallapragada, Bharadwaj (author)A popular class of methods for solving Fluid-Structure Interactions (FSI) problems computationally are the moving mesh deformation methods. These methods generally involve deforming the fluid domain so that it conforms to the structure as it undergoes changes. An efficient and robust moving mesh technique involves interpolation of displacements...master thesis 2023

van der Eijk, M. (author), Wellens, P.R. (author)The numerical prediction of two-phase flows with an interface is challenging, to a considerable extent because of the high density ratio at the interface. Numerical results become affected by momentum losses, diverging spurious interface velocities, free surface distortion, and even numerical instability. To prevent issues like these,...journal article 2023

Koshakji, Anwar (author), Chomette, Grégoire (author), Turner, Jeffrey (author), Jablonski, Jonathan (author), Haynes, Aisha (author), Carlucci, Donald (author), Giovanardi, Bianca (author), Radovitzky, Raúl A. (author)The dynamic response of flexible filaments immersed in viscous fluids is important in cell mechanics, as well as other biological and industrial processes. In this paper, we propose a parallel computational framework to simulate the fluid-structure interactions in large assemblies of highly-flexible filaments immersed in a viscous fluid. We...journal article 2023

Thedens, Paul (author), Schmehl, R. (author)Similar to parafoils, ram-air kites are flexible membrane wings inflated by the apparent wind and supported by a bridle line system. A major challenge in estimating the performance of these wings using a computer model is the strong coupling between the airflow around the wing and the deformation of the membrane structure. In this paper, we...journal article 2023

Cayon, O. (author), Gaunaa, Mac (author), Schmehl, R. (author)Soft-wing kites for airborne wind-energy harvesting function as flying tensile membrane structures, each of whose shape depends on the aerodynamic load distribution and vice versa. The strong two-way coupling between shape and loading poses a complex fluid-structure interaction problem. Since computational models for such problems do not yet...journal article 2023

Reuchlin, S.P.A. (author), Joshi, R. (author), Schmehl, R. (author)The majority of remote locations not connected to the main electricity grid rely on diesel generators to provide electrical power. High fuel transportation costs and significant carbon emissions have motivated the development and installation of hybrid power systems using renewable energy such these locations. Because wind and solar energy is...journal article 2023

van Essen, S.M. (author), Seyffert, Harleigh C. (author)Green water and slamming wave impacts can lead to severe damage or operability issues for marine structures. It is therefore essential to consider their probability and loads in design. This is difficult, as impacts are both hydrodynamically complex and relatively rare. The complexity requires high-fidelity modeling (experiments or CFD),...journal article 2023

Frei, Stefan (author), Heinlein, A. (author)The numerical simulation of atherosclerotic plaque growth is computationally prohibitive, since it involves a complex cardiovascular fluid-structure interaction (FSI) problem with a characteristic time scale of milliseconds to seconds, as well as a plaque growth process governed by reaction-diffusion equations, which takes place over several...journal article 2023

Pinto Ribeiro, A. (author), Casalino, D. (author), Ferreira, Carlos (author)This paper presents low speed fluid structure interaction simulations of a highly flexible wing at various flow conditions, including flutter and excitation from sinusoidal gusts. Such wings are becoming more relevant in recent years, due to their potential for improving aerodynamics and reducing weight, while their flutter characteristics...journal article 2023

Poland, J.A.W. (author), Schmehl, R. (author)Airborne wind energy systems using flexible membrane wings have the advantages of a low weight, small packing volume, high mobility and rapid deployability. This paper investigates the aero-structural deformation of a leading edge inflatable kite for airborne wind energy harvesting. In the first step, a triangular two-plate representation of the...journal article 2023

Aalbers, Jesper (author)This study presents the structural response of a Submerged Floating Tunnel (SFT) subjected to earthquake loading and other relevant static loading types. The SFT is a competitive solution for crossings of deep seas, canals and fjords, as it is submerged in water and floats at a fixed submersion depth. It is supported by its buoyancy and tethers,...master thesis 2022

Connector Response of a Grid Pattern Multibody Very Large Floating Structure Subject to Wave Loadingvan der Werf, Haico (author)The energy transition requires us to explore all options for generating non-fossil energy. Companies are starting to invest in technologies such as offshore floating PV systems (OFPV) to avoid congested urban population centres. OFPV structures are likely to consist of many small, simple, flexibly connected floaters. The entire structure must be...master thesis 2022

Pearse, Oliver (author)During the start-up and shutdown sequence of rocket engines, immense forces are generated that are required to propel the payload into earth's orbit or outer space. The bulk of the generated forces are in the form of thrust. However, forces are also generated that act perpendicularly to the thrust direction. These side-loads are unwanted...master thesis 2022

van Bemmel, Jeroen (author)Propellers are used to propel the vast majority of ships. They are most commonly made out of Nickel-Aluminum-Bronze alloys. This is due to their superior characteristics over other metals in terms of strength and corrosion resistance. Metal propellers are assumed to be rigid and undeformable. Current research opts to construct propellers out of...master thesis 2022
