Bashandy, Vincent (author)The current global environmental crisis has resulted in increased efforts towards more efficient and sustainable industrial processes. High-temperature heat between 150 ◦C & 400 ◦C accounts for a major part of the energy demand in industrial processes. At the same time, large quantities of waste heat are unutilised at temperatures up to 200 ...master thesis 2024

(author)In recent decades, there has been a growing focus on the management and valorization of digestate, primarily driven by its nutrient-rich composition, which positions it as a promising resource for biofertilizer production. However, several countries still restrict the direct application of digestate due to its potential environmental hazard,...journal article 2024

Della Pia, A. (author), Michelis, Theodorus (author), Chiatto, Matteo (author), Kotsonis, M. (author), De Luca, Luigi (author)This study reports the first time-resolved particle image velocimetry characterization of a planar two-phase mixing layer flow, whose velocity field is measured simultaneously in gas and liquid streams. Two parallel air and water flows meet downstream of a splitter plate, giving rise to an initially spanwise invariant configuration. The aim...journal article 2024

Lecardonnel, A. (author), de Servi, C.M. (author), Colonna, Piero (author), Laboureur, D. (author)In evaporators, the distribution of the liquid and vapor phases among the channels is a convoluted problem, depending on a wide range of parameters. However, maldistribution causes important losses of performance. Due to their complexity, the accurate modeling of such two-phase flows is difficult to handle. Hence, experimental studies are...journal article 2024

(author), De Ras, Kevin (author), Vlugt, T.J.H. (author)The use of reactive working fluids in thermodynamic cycles is currently being considered as an alternative to inert working fluids, because of the preliminarily attested higher energy-efficiency potential. The current needs to simulate their use in thermodynamic cycles, which may operate in liquid, vapour or vapour-liquid state, are an...journal article 2024

Li, H. (author)When a very viscous liquid (like oil) and a far less viscous liquid (like water) both flow through a pipeline, under certain conditions, the more viscous liquid will migrate to the core of the pipe, while being surrounded by an annulus with the less viscous liquid. This typical flow pattern, referred to as core-annular flow (CAF), was discovered...doctoral thesis 2023

Ulyanov, Boris (author)Liquid crystalline polymers have recently attracted attention for their great tensile properties. However, their interlaminar fracture toughness is low. To solve this, toughening approaches inspired by Nature are applied, exploiting the shaping freedom of fused deposition modelling. Three approaches are studied: the matchstick approach, z...master thesis 2023

Rodenburg, Sieb (author)Green hydrogen is anticipated to be pivotal in the decarbonisation of global energy systems. For the Netherlands, both domestic production and imports of green hydrogen are believed to be needed for effective decarbonisation. Yet, significant uncertainty surrounds the cost discrepancy between domestic productions and initial imports, largely...master thesis 2023

Panji Baskara Tamarona, Panji (author)Hydrogen's competitiveness as a sustainable energy carrier depends greatly on its transportation and storage costs. Liquefying hydrogen for these purposes offers benefits like purity, versatility, and higher density. However, current industrial hydrogen liquefaction processes face efficiency and cost challenges, with a second-law efficiency...master thesis 2023

ten Damme, Luuk (author)This thesis focuses on simulating the refuelling process for a liquid hydrogen-powered commercial aircraft. The liquid hydrogen is intended to flow from the refuelling truck, through a transfer line, into the aircraft’s tank using pressure feed. The numerical simulation was built upon an existing tank model, however it did not consider the...master thesis 2023
