Hobeika, N. (author), Garcia Sanchez, C. (author), Bluyssen, P.M. (author)The corona pandemic underlined a lack of Indoor Air Quality (IAQ) and<br/>ventilation. Consequently, to limit the spread of the virus, researchers explored several indicators that, through different approaches, assess IAQ and ventilation performance in indoor spaces. This paper gives an overview of those indicators and assessment methods used to...abstract 2023

Sengupta, Sampad (author), Yuan, Xun (author), Maga, L.M. (author), Pirola, S. (author), Nienaber, Christoph A. (author), Xu, Xiao Yun (author)Introduction: Thoracic endovascular aortic repair (TEVAR) of the arch is challenging given its complex geometry and the involvement of supra-aortic arteries. Different branched endografts have been designed for use in this region, but their haemodynamic performance and the risk for post-intervention complications are not yet clear. This study...journal article 2023

(author)Modeling non-ideal compressible flows in the context of computational fluid-dynamics (CFD) requires the calculation of thermodynamic state properties at each step of the iterative solution process. To this purpose, the use of a built-in fundamental equation of state (EoS) in entropic form, i.e., s= s(e, ρ), can be particularly cost-effective,...book chapter 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

Bauer, Yorrick (author)A loss of vacuum accident in the hyperloop tunnel will likely occur during its operation, and it may have a severe impact on its operational safety. Nevertheless, the hyperloop tube breach has only been researched superficially.<br/><br/>Two aerodynamic phenomena due to the breach are identified: a (quasi-)steady underexpanded jet and an...master thesis 2022

Pađen, I. (author), Garcia Sanchez, C. (author), Ledoux, H. (author)In the computational fluid dynamics simulation workflow, the geometry preparation step is often regarded as a tedious, time-consuming task. Many practitioners consider it one of the main bottlenecks in the simulation process. The more complex the geometry, the longer the necessary work, meaning this issue is amplified for urban flow simulations...journal article 2022

(author), Lamb, Hildo J. (author), Westenberg, Jos J.M. (author)Fontan patients require a balanced hepatic blood flow distribution (HFD) to prevent pulmonary arteriovenous malformations. Currently, HFD is quantified by tracking Fontan conduit flow, assuming hepatic venous (HV) flow to be uniformly distributed within the Fontan conduit. However, this assumption may be unvalid leading to inaccuracies in HFD...journal article 2021

Stokkermans, T.C.A. (author)This research is on the aerodynamics of propellers in interaction. As a propeller is dependent on the flowfield it encounters, any disturbance in that inflow results in changes in loading on the propeller. This can result in propulsive efficiency changes and affect stability through generation of in-plane forces and out-of-plane moments. The...doctoral thesis 2020
