Possibilities of Ammonia as Both Fuel and NOᵪ Reductant in Marine Engines: A Numerical Study
(MDPI, 2022-01)[Abstract] Nowadays, the environmental impact of shipping constitutes an important challenge. In order to achieve climate neutrality as soon as possible, an important priority consists of progressing on the decarbonization ... -
Analysis of the Pre-Injection System of a Marine Diesel Engine Through Multiple-Criteria Decision-Making and Artificial Neural Networks
(Mathematical Institute, Slovak Academy of Sciences, 2022-01-01)[Abstract] The present work proposes several pre-injection patterns to reduce nitrogen oxides in the Wärtsilä 6L 46 marine engine. A numerical model was carried out to characterise the emissions and consumption of the ... -
Design and Performance Analysis of a Formulation Based on SDBS and Ionic Liquid for EOR in Carbonate Reservoirs
(Elsevier B.V., 2022-02)[Abstract] A large proportion of extant crude oil is found in carbonate reservoirs worldwide. Alkylbenzene sulfonates are inexpensive anionic surfactants but they cannot be used in these reservoirs due to their incompatibility ... -
Proposed Conceptual Framework to Design Artificial Reefs Based on Particular Ecosystem Ecology Traits
(MDPI, 2022-04-28)[Abstract] Overfishing and pollution have led to marine habitat degradation, and as a result, marine fisheries are now in decline. Consequently, there is a real need to enhance marine ecosystems while halting the decline ... -
Opening or Not Opening Educational Centers in Time of SARS-CoV-2? Analysis of the Situation in Galicia (Spain)
(MDPI, 2022-05-05)[Abstract] The appearance of the SARS-CoV-2 pandemic on the world stage has implemented changes in all social activities and, therefore, in teaching at all educational levels. On the one hand, it is argued that the closure ... -
Optimization of a nature-inspired shape for a vertical axis wind turbine through a numerical model and an artificial neural network
(MDPI, 2022-08-11)[Abstract] The present work proposes an artificial neural network (ANN) to analyze vertical axis wind turbines of the Savonius type. These turbines are appropriate for low wind velocities due to their low starting torque. ... -
The technical and economic feasibility of the CENTEC floating offshore wind platform
(MDPI, 2022-09-21)[Abstract]: This paper defines a methodology for the economic feasibility analysis of a floating offshore wind farm composed of tensioned leg platforms, which are part of the EU ARCWIND research project. In this context, ... -
On the analytic explanation of experiments where turbulence vanishes in pipe flow
(Cambridge University Press, 2022-11-02)[Abstract]: The present research will provide an analytical explanation to experiments destabilising turbulence in pipe flow reported in Kuehnen et al. (Nat. Phys., vol. 14, 2018, 386–390). Those experiments show four ... -
Numerical and experimental analysis of the velocity field inside an artificial reef. Application to the Ares-Betanzos estuary
(MDPI, 2022-11-28)[Abstract]: The placement of artificial reef (AR) units on the seabed modifies the velocity field of the water, making the nutrients circulate properly and creating the necessary habitat for the settlement of the desired ... -

Application of residuals from purification of bivalve molluscs in Galician to facilitate marine ecosystem resiliency through artificial reefs with shells – One generation
(Elsevier, 2023-01-15)[Abstract] The seas and oceans of the planet provide a wide range of essential resources. However, marine ecosystems are undergoing severe degradation due to the unsustainable exploitation and consumption patterns of the ... -
Nanofluid based on 1-dodecylpyridinium chloride for enhanced oil recovery
(Elsevier, 2023-02)[Abstract] The use of nanoparticles is considered promising for enhanced oil recovery (EOR), especially when they are combined with surfactants. However, the combination of nano-sized material with surface-active ionic ... -
Multi-criteria analysis to determine the most appropriate fuel composition in an ammonia/diesel oil dual fuel engine
(MDPI, 2023-03-24)[Abstract] The possibility to employ alternative fuels is gaining special interest in the marine sector. There are several suitable candidates for traditional fossil fuels substitution. Among them, ammonia is a promising ...
