Akbaba, Kaan (author)Designing structures that are more sustainable is a relevant topic within the construction industry. By choosing materials that have a low embodied energy value and optimizing the structures that can be constructed by these materials, one could potentially minimize the economical and environmental footprint of a structural design.<br/><br/>As...master thesis 2023

Zhang, A. (author), Dieudonné, A.A.M. (author)Microbially induced carbonate precipitation is a promising ground improvement technique which can enhance the mechanical properties of soils through the precipitation of calcium carbonate. Experimental evidences indicate that the precipitated carbonate can display different distribution patterns. Crystals can develop at grain–grain contacts ...journal article 2023

Emmerink, J.V. (author), Hadi, A.H. (author), Jovanova, J. (author), Cleven, Chris (author), Schott, D.L. (author)To improve the understanding of the mixing performance of double shaft, batch-type paddle mixers, the discrete element method (DEM) in combination with a Plackett–Burman design of experiments simulation plan is used to identify factor significance on the system’s mixing performance. Effects of several factors, including three material properties...journal article 2023

Nieuwboer, B.J. (author), van Rhee, C. (author), Keetels, G.H. (author)When dredging rock using a Cutter Suction Dredger the high amount of spillage is problematic, since it prevents an energy efficient removal process. This papers presents a coupled DEM-FVM method to simulate spillage, that can be used for optimizing the design and working method of the Cutter Suction Dredger. In these simulations, the challenge...journal article 2023

Li, Jianguo (author), Wang, Bin (author), Wang, Di (author), Zhang, Pei (author), Vardon, P.J. (author)Aiming at modelling the mechanical behaviour of soil-rock mixtures accurately and efficiently, a coupled MPM-DEM formulation combining the material point method (MPM) and the discrete element method (DEM) is proposed. It is solved concurrently via the contact force linking the two individual methods. Specifically, the soil is modelled with...journal article 2023

van Kuik, Thobias (author)A magnetorheological fluid is a type of smart fluid that can change its rheological properties when a magnetic field is applied to the fluid. The fluid is a suspension of magnetizable particles in a non-magnetic carrier fluid. When a magnetic field is applied to the fluid, the particles will form structures along the magnetic field lines. These...master thesis 2022

van Gijsen, Emiel (author)For years, ESI Eurosilo have successfully stored several, mostly low-density, non free-flowing bulk materials in their silo’s. Recently, demand has arisen whether bulk materials outside their current range could be stored using the same reclaim screw system. Unfortunately, the theory behind the screw dates from the 1980s and assumes fine...master thesis 2022

Nieuwboer, B.J. (author)Due to an increased demand for transport, ships become larger, needing a larger navigable depth. For these reasons a waterway needs to be dredged and a Cutter Suction Dredger is a vessel suitable for this operation.<br/><br/>A Cutter Suction Dredger is a floating vessel which removes sand, clay or soft rock from sea or river beds. It has a...doctoral thesis 2022

Hageman, Evelien (author)Over 5000 offshore wind turbine generators have been installed in the past decades. 80% of these wind turbines have a monopile foundation. Monopiles are hollow steel tubular piles with a diameter of up to 10m. The first phase of the monopile installation consists of the self-weight penetration into the seabed due to the mass of the monopile....master thesis 2022

Guo, Y. (author), Shi, Can (author), Zhao, Chunfa (author), Markine, V.L. (author), Jing, Guoqing (author)Crumb rubber (CR) has been proposed to apply in the ballast or sub-ballast layer for ballast degradation mitigation and vibration (noise) reduction. The CR can change the ballast layer stiffness, which can affect the train-track-subgrade dynamic performance and cause travel comfort and safety issues. Towards this, this study aims at...journal article 2022

Zhang, Zhihai (author), Xiao, Hong (author), Wang, Y. (author), Fang, Jia (author), Nadakatti, M. M. (author), Wang, Haoyu (author)The lateral resistance of ballast bed is an important parameter to prevent track expansion and maintain track stability. The invasion of sand particles can cause the change of lateral resistance of ballast bed and affect the stability of track structure, but little attention has been paid to the change characteristics of nonlinear lateral...journal article 2022

(author)Galvanized steel scrap flow and injection into the HIsarna reactor are investigated using discrete element method (DEM). The scrap particle is fed into the reactor through an inclined chute and hits the slag surface where the zinc content is evaporated and solid particles melt. A DEM model is setup and validated using experimental data...journal article 2022

Gilvari, H. (author)Presently, biomass pellets play a significant role in energy transition scenarios worldwide. Due to the lack of local supplies, many countries import their pellets from countries with enormous resources. For instance, in Europe, a big share of pellets is imported from the USA, Canada, and Asian countries. Pellets are normally transferred in bulk...doctoral thesis 2021
