Verbeek, Merel C. (author), Talstra, H. (author), Labeur, R.J. (author), Uijttewaal, W.S.J. (author)Tidal stream turbines are becoming an affordable option for harvesting sustainable energy in coastal areas. They can be retrofitted in barrages, providing an integral solution for flood protection and emission-free power generation, within environmental constraints. To optimize the turbine-barrage configuration with respect to these...journal article 2024

Aoun, J. (author)As the deployment of new railway technologies requires official approval from local authorities and governmental agencies, a well-specified strategy can foster investment decisions for technological developments and the overall system migration process. Therefore, it is crucial to guarantee that the proposed railway technologies can enhance...doctoral thesis 2023

Li, Z. (author), Chen, Y. (author), Provis, John L. (author), Cizer, Özlem (author), Ye, G. (author)This paper provides a critical review on autogenous shrinkage of alkali-activated slag (AAS). It is reported that AAS paste, mortar, and concrete generally show larger autogenous shrinkage than Portland cement (PC) counterparts. Self-desiccation is the main driving force of the autogenous shrinkage of hardened AAS, but other mechanisms also...review 2023

Tieleman, O.C. (author)Flood gates form an essential part of many flood defence systems in coastal areas. During storm events, these gates are subjected to extreme loads from various sources. This dissertation addresses the dynamic behaviour of flood gates induced by wave impacts. A semi-analytical fluid-structure interaction model is developed to predict vertical...doctoral thesis 2022

Odriozola, Magela (author)Anaerobic membrane bioreactor (AnMBR) technology is increasingly researched for wastewater treatment in a circular economy scenario to recover nutrients, water, and biogas. AnMBR couples the advantages of anaerobic digestion, such as low sludge production, no aeration requirement and biogas production, with the benefits of membrane technology,...doctoral thesis 2022

Huang, Y. (author), Grunewald, S. (author), Schlangen, E. (author), Lukovic, M. (author)Ultra-High Performance Fiber-Reinforced Concrete (UHPFRC) is, due to its superior mechanical properties and low permeability, a promising material for the restoration and improvement of the mechanical resistance and durability of existing Reinforced Concrete (RC) structures. This paper reviews the strengthening applications of UHPFRC in flexure,...review 2022

Langer, J.K.A. (author), Infante Ferreira, C.A. (author), Quist, J.N. (author)Ocean Thermal Energy Conversion (OTEC) produces electricity using the temperature difference between warm surface and cold deep-sea water. OTEC systems in literature only limitedly consider seasonal seawater temperature<br/>variations and thus might not be adequately sized for off-design conditions. This potentially leads to techno-economically...journal article 2022

(author), Starkova, Olesja (author)Service lifetimes of polymers and polymer composites are impacted by environmental ageing. The validation of new composites and their environmental durability involves costly testing programs, thus calling for more affordable and safe alternatives, and modelling is seen as such an alternative. The state-of-the-art models are systematized in...review 2022

This is achieved by maintaining the part of the coast that support these functions; the coastal foundation. The coastal foundation is maintained by means of sand nourishments. Up to now, it has been assumed that net transports across the coastal foundation's...journal article 2022

Tas, S.A.J. (author), van Maren, D.S. (author), Helmi, Muhammad (author), Reniers, A.J.H.M. (author)A chenier is a beach ridge, consisting of sand and/or shells, overlying a muddy substrate. In this paper, we explore the cross-shore dynamics of cheniers in their ‘active’ phase, i.e. the phase between their formation and their landing on the shore and can no longer be reached by daily wave and tidal influences. While cheniers described in...journal article 2022

Huang, X. (author), Tummers, M.J. (author), van Veen, E.H. (author), Roekaerts, D.J.E.M. (author)The flamelet generated manifold (FGM) model is suitable for moderate or intense low oxygen dilution (MILD) combustion provided the flamelets underlying the manifold include the effects of strong dilution by products of the fuel/oxidizer mixture. Here we propose such an extended model based on the use of non-premixed flamelets diluted at the...journal article 2022

van Dijk, E.J.H. (author), Haaksman, V.A. (author), van Loosdrecht, Mark C.M. (author), Pronk, M. (author)In this study a mathematical framework was developed to describe aerobic granulation based on 6 main mechanisms: microbial selection, selective wasting, maximizing transport of substrate into the biofilm, selective feeding, substrate type and breakage. A numerical model was developed using four main components; a 1D convection/dispersion...journal article 2022

van Wee, G.P. (author), Kroesen, M. (author)The literature has increasingly recognized that people's attitudes can change for many reasons. This paper argues that attitude changes can have important implications for modelling travel behaviour and ex ante evaluations of candidate policy options. Limiting ourselves to the transport system and the built environment, we discuss why attitudes...journal article 2022

Jolly, Mark (author), Katgerman, L. (author)Over the last 4 decades, remarkable progress has been made in the modelling of casting processes. The development of casting models is well reflected in the proceedings of the 15 Modelling of Casting, Welding and Advanced Solidification Processes (MCWASP) conferences that have been held since 1980. Computer simulations have enabled a better...journal article 2022
