Lighter and faster simulations on domains with symmetries
(Elsevier, 2024-05-15)
Article
Accés obertA strategy to improve the performance and reduce the memory footprint of simulations on meshes with spatial reflection symmetries is presented in this work. By using an appropriate mirrored ordering of the unknowns, discrete ... -
Ultrafast multi-photon excitation of ScVO4:Bi3+ for luminescence thermometry
(2022-01-01)
Article
Accés obertWe demonstrate a multi-photon excitation (MPE) scheme for luminescence thermometry using ScVO4:Bi3+. MPE is performed using a 37 fs Ti:sapphire laser pulse centered at 800 nm. Log-log plots of the phosphorescence intensity ... -
Review of the uses of acoustic emissions in monitoring cavitation erosion and crack propagation
(MDPI AG, 2024-02-24)
Article
Accés obertNowadays, hydropower plants are being used to compensate for the variable power produced by the new fluctuating renewable energy sources, such as wind and solar power, and to stabilise the grid. Consequently, hydraulic ... -
Parametric study of structured thermocline storage systems
(2022)
Text en actes de congrés
Accés restringit per política de l'editorialA thermal accumulator system for concentrated solar power is modeled to perform a parametric study. The thermal accumulation system is a type of structured thermocline where there is a solid filler material with some ... -
Optimized approach for CFD simulations of HVAC systems with grill air diffusers
(International Institute of Refrigeration, 2023)
Text en actes de congrés
Accés restringit per política de l'editorialA proper CFD simulation of air distribution within a room requires the correct representation of inlet conditions from ventilation grids. Those elements are usually characterized by blades with a certain inclination angle ... -
DNS and RANS simulations of a coil heat exchanger immersed in a tank
(Begell House, 2023)
Comunicació de congrés
Accés restringit per política de l'editorialThe operation of heat exchangers in a thermal system can be described by simple heat transfer equations. The heat exchange is normally defined by a global heat transfer coefficient, which takes into account internal and ... -
Energy analysis of resilient cooling technologies in Mediterranean buildings – A case study
(International Building Performance Simulation Association (IBPSA), 2023)
Text en actes de congrés
Accés restringit per decisió de l'autorBuildings represent 40% of energy consumption and residential buildings accounted for 27% of final energy consumption in Europe. It could be even more due to the effects of climate change. The severity of weather will ... -
Toward the usage of deep learning surrogate models in ground vehicle aerodynamics
(Multidisciplinary Digital Publishing Institute (MDPI), 2024-03-27)
Article
Accés obertThis study introduces a deep learning surrogate model designed to predict the evolution of the mean pressure coefficient on the back face of a Windsor body across a range of yaw angles from 2.5◦ to 10◦ . Utilizing a ... -
Biobased imine vitrimers obtained by photo and thermal curing procedures-promising materials for 3D printing
(American Chemical Society (ACS), 2024-03-14)
Article
Accés obertImine-based vitrimers were prepared from synthesized diimine-dimethacrylate monomer derived from biobased vanillin. First, a methacrylate derivative starting from vanillin was synthesized. The diimine derivative was ... -
Contactless characterization of the elastic properties of glass microspheres
(American Institute of Physics (AIP), 2023-04-25)
Article
Accés obertGlass microspheres are of great interest for numerous industrial, biomedical, or standalone applications, but it remains challenging to evaluate their elastic and optical properties in a non-destructive way. In this work, ... -
Far-field radiative thermal rectification based on asymmetric emissivity
(American Chemical Society (ACS), 2023-09-29)
Article
Accés obertThis experimental study investigates thermal rectification via asymmetric far-field thermal radiation on a fused silica slab. An asymmetrical distribution of surface emissivity is created over the device by partially ... -
Harnessing disulfide and transesterification bond exchange reactions for recyclable and reprocessable 3D-printed vitrimers
(2024-02-01)
Article
Accés obertTwo new vitrimeric materials have been studied for potential additive manufacturing applications such as 3D- printing. A monomer containing disulfide bonds and ß-hydroxyesters was easily synthesized from two low- cost and ...
