Hierarchical Upscaling of Data-Driven Damage Diagnostics for Stiffened Composite Aircraft StructuresBroer, Agnes A.R. (author), Yue, N. (author), Galanopoulos, Georgios (author), Benedictus, R. (author), Loutas, Theodoros (author), Zarouchas, D. (author)To move towards a condition-based maintenance practice for aircraft structures, design of reliable health management methodologies is required. Development of diagnostic methodologies is commonly realised on simplified sample structures with assumptions that methodologies can be adapted for application to realistic aircraft structures under...conference paper 2023

van Nieuwkerk, Pelle (author)The United Nations’ Paris Agreement forces nations and industries to transition from conventional hydrocarbon-based energy sources to more sustainable and less-emitting alternatives such as geothermal energy. Geothermal doublets are used to provide a source of green heat to greenhouses and residential buildings. In industry, reservoir simulators...master thesis 2022

Bezemer, Jelle (author)Limiting maximum crack widths is a serviceability limit state, which ensures the durability of reinforced structures. In current practice, maximum crack widths are limited by using additional reinforcement, on top of the amount of reinforcement required for the designed ultimate bearing capacity. Reducing the amount of reinforcing steel used,...master thesis 2022

Bellinga, Willem Jelle (author)Mangrove is a coastal vegetation type primarily located in the tropical regions between 5 North and 5 South. This coastal vegetation is capable of reducing the force of incoming waves. This is a result of the obstruction created by the roots, stems and canopies against waves to propagate through. Because of this capability, mangrove vegetation...master thesis 2022

Wang, L. (author), Golfier, Fabrice (author), Tinet, Anne-Julie (author), Chen, Weizhong (author), Vuik, Cornelis (author)This work investigates numerical method and equivalent continuum approach (ECA) of fluid flow in fractured porous media. The commonly used discrete fracture model (DFM) without upscaling needs full discretization of all fractures. It enjoys the merit of capturing each fracture accurately but will get in trouble with mesh partition and low...journal article 2022

Langer, J.K.A. (author), Quist, J.N. (author), Blok, K. (author)Ocean Thermal Energy Conversion (OTEC) is a promising renewable energy technology that is the most economical at large scale. But contemporary literature does not address how OTEC could reach such scale with current technology, and what the techno-economic impact of location-dependent factors and technological learning are. This paper tackles...journal article 2022

Lesueur, M.J.B.P. (author), Guével, Alexandre (author), Poulet, Thomas (author)Modelling anisotropic flow in rocks requires their full permeability tensor. While theories derived from the upscaling of Stokes flow to Darcy's law may justify the tensor symmetry, homogenisations from micro-scale rock samples often return a non-zero level of asymmetry. Since most studies dismiss these controversial observations as numerical...journal article 2022

Lesueur, M.J.B.P. (author), Rattez, Hadrien (author), Colomes, Oriol (author)Flow simulations on porous media, reconstructed from Micro-Computerised Tomography (μCT) scans, is becoming a common tool to compute the permeability of rocks. Still, some conditions need to be met to obtain accurate results. Only if the sample size is equal or larger than the Representative Elementary Volume will the computed effective...journal article 2022

Lesueur, M.J.B.P. (author), Veveakis, Manolis (author), Rattez, Hadrien (author)Digital Rock Physics has reached a level of maturity on the characterisation of primary properties that depend on the microstructure - such as porosity, permeability or elastic moduli - by numerically solving field equations on μCT scan images of rock. After small deformations or at depth though, most rocks eventually reach their limit of...journal article 2022

Mathew, R. (author)This dissertation presents a study of fine sediment transport and morphodynamics in estuarine settings using data from the Lower Passaic River (LPR), located in New Jersey, USA. Originally a relatively shallow system, it has been dredged and deepened for navigation purposes from the late-1800s onwards, along with other modifications such as...doctoral thesis 2021

Subramanian, Aswath (author)Perovskite Solar Cells are an increasing attraction in research with great strides in performance efficiencies. But their commercialization is far from fruition, due to persistent issues. Stability under prolonged exposure to external stresses is a major concern. Furthermore, the adaption of upscaling technologies in research is presently slow....master thesis 2021

Yilmaz, Ozal (author)The development of a wind farm is a highly sophisticated task, whereby many stakeholders are involved and several unique disciplines come together to form a whole. Commonly, the unique disciplines are optimized individually which leads to sub-optimal windfarm designs. Therefore, it is of great importance that an interdisciplinary approach is...master thesis 2021

Souaid, C. (author), van der Heijden, H.M.H. (author), Elsinga, M.G. (author)After more than ten years since the introduction of Near Zero-Energy Buildings (NZEBs), the transition towards a zero-energy new built environment can still be considered slow despite European Member States’ various efforts to facilitate, promote and accelerate their implementation and uptake. The barriers to sustainability measures in general...journal article 2021

Li, L. (author), Voskov, D.V. (author)We present a multi-level discrete fracture model (MLDFM) to guarantee a robust and efficient solution for naturally fractured reservoir simulation. In MLDFM, we apply a triple continuum model using structured grid for forward simulation where large-scale fractures are represented with numerical embedded discrete fracture model (EDFM) and the...journal article 2021

Verbeeten, Gijs (author)During the past decade, the offshore wind energy industry evolved to bigger turbines, going into deeper waters and farther offshore. As bottom-fixed wind turbines are limited to shallow water depths, floating wind structures are the next frontier to unlock the vast potential of wind energy. Despite many techno-economic challenges, several full...master thesis 2020
