Seasonal Analysis Comparison of Three Air-Cooling Systems in Terms of Thermal Comfort, Air Quality and Energy Consumption for School Buildings in Mediterranean Climates
(MDPI, 2021)Efficient air-cooling systems for hot climatic conditions, such as Southern Europe, are required in the context of nearly Zero Energy Buildings, nZEB. Innovative air-cooling systems such as regenerative indirect evaporative ... -
Seasonal energy efficiency ratio of regenerative indirect evaporative coolers—Simplified calculation method
(Elsevier, 2023)Evaporative-cooling technology is a promising alternative to conventional air-cooling systems that are based on using direct expansion units in terms of energy efficiency. Seasonal energy efficiency ratio (SEER) calculation ... -
Selection of Parameters and Strategies to Reduce Energy Consumption and Improve Surface Quality in EN-AW 7075 Molds Machining
(MDPI, 2018)The machining of cavities for blow molding is a long and costly process, with the objective of obtaining an excellent surface finish with the minimal possible electrical energy consumption (EEC). This work has studied ... -
Simplified performance correlation of an indirect evaporative cooling system: Development and validation
(Elsevier, 2018)At present, there is an increasing interest in indirect evaporative coolers (IEC), which are an effective alternative to conventional cooling systems due to their high efficiency. In this study a new simplified first order ... -

Software Tool for Acausal Physical Modelling and Simulation
(MDPI, 2019)Modelling and simulation are key tools for analysis and design of systems and processes from almost any scientific or engineering discipline. Models of complex systems are typically built on acausal Differential-Algebraic ... -
Stiction compensation for low-cost electric valves
(Elsevier, 2023)Nonlinear dynamics of control valves, such as stiction, can produce significant performance degradation in the control loops where they are involved. There are several works in the literature describing and modelling these ... -
Stochastic Flow Analysis for Optimization of the Operationality in Run-of-River Hydroelectric Plants in Mountain Areas
(MDPI, 2024)The highly temporal variability of the hydrological response in Mediterranean areas affects the operation of hydropower systems, especially in run-of-river (RoR) plants located in mountainous areas. Here, the water flow ... -
Stripping of PFA Fluoropolymer Coatings Using a Nd:YAG Laser (Q-Switch) and an Yb Fiber Laser (CW)
(MDPI, 2019)Fluoropolymers such as PFA are used as coatings for the protection of metal substrates due to their high chemical inertia and non-stick properties. These are “wear and tear” coatings and they degrade, at which point they ... -
Study of the Dependence of Solar Radiation Regarding Design Variables in Photovoltaic Solar Installations with Optimal Dual-Axis Tracking
(MDPI, 2021)Solar tracking is an efficient strategy to increase the radiative capture of photovoltaic collectors. Within the multiple efforts made in recent decades to improve the production of these facilities, various works have ... -
Study on the Main Influencing Factors in the Removal Process of Non-Stick Fluoropolymer Coatings Using Nd:YAG Laser
(MDPI, 2019)The coatings with fluoropolymer resins rich in fluorinated ethylene propylene (FEP) and polytetrafluoroethylene (PTFE) are applied as anti-adherent coatings on aluminum–magnesium substrates for use in food containers. In ... -
Superhydrophobic Cerium-Based Coatings on Al-Mg Alloys and Aluminized Steel
(MDPI, 2019)Aluminum-magnesium (Al-Mg) alloy and aluminum-coated steel (aluminized steel) are typically used for the manufacturing of baking trays and molds. For these applications, these materials must be modified to develop release ... -
Ternary Blends for Self-Compacting Mortars Production Composed by Electric Arc Furnace Dust and Other Industrial by-Products
(MDPI, 2022)This study is framed within the circular economy model through the valorisation of industrial by-products. This research shows the results of producing self-compacting mortars (SCMs) with electric arc furnace dust (EAFD) ... -
The influences of the variable speed and internal die geometry on the performance of two commercial soluble oils in the drawing process of pure copper fine wire
(Springer, 2021)The cold wiredrawing process constitutes a classical-tribological system in which a stationary tribe-element (die) is in contact with a tribe-element in relative motion (wire) and both interacting with the interfacial ... -
The Inhibitive Effect of Sebacate-Modified LDH on Concrete Steel Reinforcement Corrosion
(MDPI, 2022)In recent decades, layered double hydroxides (LDH) have been proposed as innovative corrosion inhibitors for reinforced concrete. Their protective action is based on the ability to intercalate specific anions in the ... -
The role of pH on leaching of heavy metals and chlorides from electric arc furnace dust in cement-based mortars
