Performance assessment of an experimental CO2 transcritical refrigeration plant working with a thermoelectric subcooler in combination with an internal heat exchanger
(Elsevier, 2022)
Artículo / Artikulua,
Regulations in the refrigeration sector are forcing the transition to low global warming potential fluids such as carbon dioxide in order to decrease direct greenhouse gases emissions. Several technologies have arisen over ...
Analysis of product shrinkage and waste in a potato bagging plant
(Dime University of Genoa, 2022)
Contribución a congreso / Biltzarrerako ekarpena,
Nowadays, an average of 2 kg of waste per person are generated in Spain. Furthermore, the household consumption is rising and, as a consequence, the waste production is also increasing. This trend presents a direct impact ...
Development of a water flow and velocity optical fiber sensor for field testing
(Optica Publishing Group, 2022)
Contribución a congreso / Biltzarrerako ekarpena,
A water flow and velocity fiber optic sensor system was developed and tested. The sensing head was especially developed and ruggedized to measure velocities at different depths, in order to calculate the discharge in channels.
Thermal expansion behaviour of Invar 36 alloy parts fabricated by wire-arc additive manufacturing
(Elsevier, 2022)
Artículo / Artikulua,
Invar 36 alloy is of high interest in various industrial sectors, due to its reduced thermal expansion properties. This study aims to validate Wire-Arc Additive Manufacturing (WAAM) technology as a valid method for ...
Techno-economic evaluation of the performance of an innovative rotary disk receiver concept in a CSP power plant
(AIP Publishing, 2022)
Contribución a congreso / Biltzarrerako ekarpena,
This study evaluates the thermal performance of an innovative discs receiver and models its effect in a CSP
plant. Energetic and economic results were compared with a foam receiver developed in the European project ...
Calculation of intercepted photosynthetically active radiation (IPAR) for traditional crops in Castilla y León, Spain
(Universidad Carlos III, 2022)
Contribución a congreso / Biltzarrerako ekarpena,
Agriculture is one of the most important economic activities in the Castilla y León region (Spain),
approximately one-third of the land area is destined for this use. The role of agriculture in rural areas
is essential ...
Estimation of the solar thermal power generation potential in Pamplona (northern Spain)
(Universidad Carlos III, 2022)
Contribución a congreso / Biltzarrerako ekarpena,
In this work, an analysis of the potential of the city of Pamplona to produce solar thermal
energy was carried out, according to the solar radiation received. As a result, for each
residential, industrial, or service ...
An alternative methodology for the evaluation of photocatalytic activity of polymeric coatings by monitoring dye degradation
(MDPI, 2022)
Artículo / Artikulua,
This work provides an alternative method for evaluating the photodegradation behaviour of different types of dyes such as Methylene Blue, Rhodamine B, Congo Red, Metanil Yellow, and Malachite Green. In this methodology, ...
Mechanical performance of AlCrSiN and AlTiSiN coatings on inconel and steel substrates after thermal treatments
(MDPI, 2022)
Artículo / Artikulua,
The objective of this study was to explore the mechanical properties of AlCrSiN and AlTiSiN coatings deposited on Inconel and steel substrates after thermal treatments of 500 °C and 800 °C. Nanoindentation was used to ...
Thermoelectric heating and air conditioning with double flux ventilation in passive houses
(2022)
info:eu-repo/semantics/doctoralThesis,
Esta tesis propone el uso de bombas de calor basadas en termoelectricidad, cuyas ventajas competitivas se basan fundamentalmente en la ausencia de partes móviles y de refrigerantes. Concretamente, esta tesis se centra en ...
