Numerical Modelling of a Floating Wind Turbine Semi-Submersible Platform
(MDPI, 2021-11-28)
A detailed study is undertaken of the computational modelling of a sub-platform for floating offshore wind using the software Star-CCM+ with the application of the RANS approach. First, a mathematical introduction to the ...
Estudio movimiento de metal líquido a velocidades mayores de 1 M/S.
(2022-12-14)
La industria de la fundición es un sector que ha de mejorar un proceso defabricación con muchos procesos físicos distintos, y en condiciones críticas. Esto implicamuchas variables que hacen que el proceso se encarezca ...
Uncertainty and detection limits of Pu-241 determination by liquid scintillation counting (LSC)
(Elsevier, 2021-10)
[EN]Determination of Pu-241 is an essential issue for radiation protection, as it is the precursor of some nuclides with high radiotoxicity. Pu-241 is a low energy beta emitter, which makes its measurement more challenging ...
Low-grade RC beams strengthened with TRM composite based on basalt, carbon and steel textiles: Experimental and analytical study
(Elsevier, 2022-06)
This study develops an easy-to-conduct numerical calculation method to assess the effect of Textile Reinforced Mortar when used as externally bonded flexural strengthening technique in low-grade reinforced concrete beams ...
Decoupling the heat loss coefficient of an in-use office building into its transmission and infiltration heat loss coefficients
(Elsevier, 2021-11)
[EN]The actual building energy performance essentially depends on the building occupant's behaviour, the real performance of the installed energy systems and the in-use performance of the building envelope. The thermal ...

(2022-11-18)
La presente tesis doctoral analiza las diferentes estrategias de modelado de motores diésel marinos existentes en el marco de su diagnosis y mantenimiento basado en condiciones. Concretamente, tras una fase preliminar en ...
Long-term assessment of the thermal stability of sodium nitrate-urea eutectic phase change material
(Elsevier, 2021-09-15)
The eutectic mixture formed by urea and sodium nitrate can be an interesting candidate for use as a phase change material for thermal energy storage in space heating and domestic hot water applications. It shows a melting ...
Quantification of the influence of the C, Cr and P contents on the permeability of hydrogen through Fe alloys
(Elsevier, 2022-03)
[EN] Ferritic-martensitic steels are candidate materials for blanket structural components of future thermonuclear fusion reactors. However, the tritium inventory that can be retained in different components of the reactor ...

(Springer, 2021-07-15)
Purpose This article aims to estimate the social footprint of a higher education institution (HEI) and its potential contribution to Sustainable Development Goals (SDGs) under life cycle assessment (LCA) perspective. The ...
Design and Operation of a Polygeneration System in Spanish Climate Buildings under an Exergetic Perspective
(MDPI, 2021)
This work defines and analyzes the performance of a polygeneration system in five different locations in Spain to maintain the thermal comfort and air quality of an office building. The facility is based on a chiller and ...
