Rowther, Sahl (author), Nealon, Rebecca (author), Meru, Farzana (author), Wurster, James (author), Aly, H.A. (author), Alexander, Richard (author), Rice, Ken (author), Booth, Richard A (author)We carry out three-dimensional smoothed particle hydrodynamics simulations to study the role of gravitational and drag forces on the concentration of large dust grains (St > 1) in the spiral arms of gravitationally unstable protoplanetary discs, and the resulting implications for planet formation. We find that both drag and gravity play an...journal article 2024

Volger, R. (author), Puiman, L. (author), Haringa, C. (author)The growing global population and heightened concern for climate change leads to increased interest in utilizing microbial fermentations to replace polluting production processes for e.g., plastics, fuels, and animal proteins. Computational fluid dynamics (CFD) is a valuable tool for accelerating the scale-up and optimization of large-scale...review 2024

Nijssen, Tim M.J. (author), Padding, J.T. (author), Ottens, M. (author)The hydrodynamics of the Expanded Bed Adsorption process is studied through simulations combining Computational Fluid Dynamics and the Discrete Element Method. A representative base case is defined, based on process design parameters commonly encountered in literature. Then, 19 other cases are defined, each representing a singular adjustment...journal article 2023

Du, Zhe (author), Negenborn, R.R. (author), Reppa, V. (author)Transportation of a large offshore platform from inland waters to the open sea is a hazardous and challenging mission. With the development of the autonomous surface vessel (ASV), the problem of large floating object transportation has a chance to be solved by applying multiple physical-connected autonomous tugboats. This article proposes a...journal article 2023

Begall, Moritz J. (author), Schweidtmann, A.M. (author), Mhamdi, Adel (author), Mitsos, Alexander (author)Computational Fluid Dynamics (CFD) is a powerful tool which can help with the geometry optimization of continuous milli-scale reactors, which often are highly complex devices. Attempting to perform this optimization by manually modifying and testing geometry configurations can however be tedious and computationally inefficient. Addressing...journal article 2023

Deng, Z. (author)Flocculation is an important process in fine cohesive sediment transport that still requires investigation as it is a complex process, involving the aggregation, break-up and reconformation of mineral and biological particles.<br/>Fine cohesive sediments are found in rivers, estuaries and their adjacent areas. With the rapid economic development...doctoral thesis 2022

Junge, Kai (author), Obayashi, Nana (author), Stella, F. (author), Della Santina, C. (author), Hughes, Josie (author)Biology provides many examples of how body adaption can be used to achieve a change in functionality. The feather star, an underwater crinoid that uses feather arms to locomote and feed, is one such system; it releases its arms to distract prey and vary its maneuverability to help escape predators. Using this crinoid as inspiration, we develop a...journal article 2022

Kleiberg, T.N.J. (author), Tieleman, Orson (author), Versluis, Marco (author), Kortlever, Wim (author), ten Oever, Erik (author), Hofland, Bas (author)This paper presents a novel design method to predict fatigue of flood gates due to dynamic wave loading. The accumulation of fatigue damage is predicted probabilistically over the entire lifetime of the structure rather than with a set of normative events. Load events are defined using a joint probability distribution of historical wind and...journal article 2022

(author), Van Dalen, Jeroen (author), Ysebaert, Tom (author), Bouma, T.J. (author)Tidal flats are biogeomorphic landscapes, shaped by physical forces and interaction with benthic biota. We used a metabolic approach to assess the overarching effect of bioturbators on tidal landscapes. The benthic bivalve common cockle (Cerastoderma edule) was used as model organism. The effect of C. edule on sediment resuspension was...journal article 2021

de Vet, P.L.M. (author)Intertidal flats — regions of estuaries that emerge every tide from the water — form unique ecosystems. Benthic communities living in the bed are a valuable food source for wading birds. Salt marshes present on these flats further enhance the biodiversity. Through the damping of waves, intertidal flats also contribute to the safety of the...doctoral thesis 2020

Keijdener, C. (author)The Arctic presents a great opportunity for two major industries. First, since the region is expected to contain a significant amount of hydrocarbon reserves, it is very attractive for the oil and gas industry. Second, the receding extent of sea ice is making the region more accessible for shipping and, therefore, an opportunity is emerging for...doctoral thesis 2019
