Fradera Soler, Pau (author)Pollution in urban environments is increasingly becoming a major concern for our societies which, together with the increasingly powerful capabilities provided by computational fluid dynamics (CFD), has made pollution dispersion a common topic of research during the last two decades. Several factors are relevant to the dispersion of pollutants...master thesis 2023

Mouri Sardar Abadi, P. (author), Baluch, Abrar H. (author), Sebaey, T. A. (author), Peeters, D.M.J. (author), Barzegar, M. (author), Lopes, C. S. (author)This work aims to improve the flexural behaviour of unidirectional fibre-reinforced laminates by means of coupling an optimization procedure for quasi-isotropic configurations with the design space opened by dispersed-ply orientations. The design approach consists of finding suitable alternatives to traditional laminates (with fibre...journal article 2023

Makris, K. (author), Langeveld, J.G. (author), Clemens-Meyer, François H.L.R. (author), Watts, Joanna (author), Begum, Hasina (author), Horoshenkov, Kirill V. (author)This article explores the potential of vibro-acoustics to detect physical ageing of plastic pipes. For this purpose, two different topics are combined: the ability of vibro-acoustics to estimate the storage modulus of a plastic pipe, and the sensitivity of the estimated storage modulus to changes due to ageing. Concerning the first topic, a...journal article 2023

Hobeika, N. (author), Garcia Sanchez, C. (author), Bluyssen, P.M. (author)The COVID-19 pandemic highlighted the importance of indoor air quality (IAQ) and ventilation, which researchers have been warning about for years. During the pandemic, researchers studied several indicators using different approaches to assess IAQ and diverse ventilation systems in indoor spaces. To provide an overview of these indicators and...review 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

Ocampo Mendoza, Alonso (author)Overcoming the intermittency problem of renewable energy is an issue that has to be addressed in order to achieve an efficient energy system. Hydrogen has been gaining interests, as green energy carrier, which is included in the energy transition plans of not only the Netherlands, but worldwide. Due to its physical characteristics, large scale...master thesis 2022

Hooyberghs, H. (author), De Craemer, S. (author), Lefebvre, W. (author), Vranckx, S. (author), Maiheu, B. (author), Trimpeneers, E. (author), Vanpoucke, C. (author), Janssen, S. (author), Meysman, F.J.R. (author), Fierens, F. (author)Detailed validation of air quality models is essential, but remains challenging, due to a lack of suitable high-resolution measurement datasets. This is particularly true for pollutants with short-scale spatial variations, such as nitrogen dioxide (NO<sub>2</sub>). While street-level air quality model chains can predict concentration...journal article 2022

Engler Faleiros, D. (author), van den Bos, W. (author), Botto, L. (author), Scarano, F. (author)This work describes a modelling approach to SARS-CoV-2 dispersion based on experiments. The main goal is the development of an application integrated in Ansys Fluent to enable computational fluid dynamics (CFD) users to set up, in a relatively short time, complex simulations of virion-laden droplet dispersion for calculating the probability...journal article 2022

Helmons, R.L.J. (author)There is an expected increase in demand of critical raw materials, e.g. nickel and cobalt, mainly driven by the shift towards renewable energy solutions and the increase in production of electric vehicles. That trend has raised the interests for the mining of polymetallic nodules. The most extensive nodule depostions are found on the abyssal...conference paper 2022

Geyer, A. (author), Quirchmayr, Ronald (author)We develop a Korteweg-De Vries (KdV) theory for weakly nonlinear waves in discontinuously stratified two-layer fluids with a generally prescribed rotational steady current. With the help of a classical asymptotic power series approach, these models are directly derived from the divergence-free incompressible Euler equations for unidirectional...journal article 2022

Hadžiabdić, Muhamed (author), Hafizović, Mahir (author), Ničeno, Bojan (author), Hanjalic, K. (author)We report on the application and comparative assessment of two rational turbulence modelling approaches for the computer simulation of air flow and pollutant dispersion in real urban environment: a stand-alone unsteady Reynolds-averaged Navier-Stokes eddy-viscosity model (URANS), and its blend with Large-eddy simulations (LES) in a hybrid...journal article 2022

Huijer, A.J. (author), Kassapoglou, C. (author), Pahlavan, Lotfollah (author)The recording and processing of acoustic emissions can be used to identify and localise damage mechanisms occurring in engineering structures. In plate-like structures, acoustic emissions propagate through the structure as guided waves. With a measurement location away from the source location, dispersion effects in the guided wave distort...conference paper 2022

(author), Kooiman, Klazina (author)Bacteria encased in a biofilm poses significant challenges to successful treatment, since both the immune system and antibiotics are ineffective. Sonobactericide, which uses ultrasound and microbubbles, is a potential new strategy for increasing antimicrobial effectiveness or directly killing bacteria. Several studies suggest that...journal article 2022

Kausel, Eduardo (author), de Oliveira Barbosa, J.M. (author)This article presents a set of close approximations to model an elastic half-space supporting an embankment, which are evaluated in the context of phase velocity spectra, i.e. in terms of the normal wave propagation modes of the embankment-half-space system. The ultimate, intended target of these approximations is in the modeling of...journal article 2022

(author)An idealized width-averaged model is employed to study the influence of wind stress on subtidal salt intrusion and stratification in well-mixed and partially stratified estuaries. We show that even in mild conditions, wind forcing can influence the estuarine salinity structure in a substantial way. By studying the role of wind forcing on...journal article 2022

Maat, Sander (author)The goal of this study is to test out the accuracy of the upscaling approach (Jinyu Tang, 2021) for a geothermal doublet. This approach tries to simulate the physical thermal dispersion. When modeling in a geothermal reservoir it would be easy if a lot of layers can be upscaled. However, when doing upscaling one can not just take an average of...bachelor thesis 2021
