Vertical Axis Wind Turbines: Current Technologies and Future Trends
(2015-04)
[Abstract] This paper, based on the pursuit of scientific articles published and recorded in the last five years (2010-2014) patents on VAWT technology, gives an image of the current situation of the treated ...
Ensayos experimentales para la obtención del coeficiente hidráulico como un factor relevante en el desarrollo del proyecto de un buque
(2010-11-15)
[Resumen]En este artículo se presenta un estudio experimental del comportamiento de un modelo sujeto a la inundación progresiva de sus compartimentos. El estudio consta de varios
ensayos mediante los que se inunda uno o ...
Undulating Propulsion System Design
(AEIPRO (Spanish Association of Project Engineering), 2010)
[Abstract] Throughout history the practical implementation of propulsion mechanisms in the fluid environment based on the rotation has been easier to deal because of the state of the art in its time, and this has meant ...
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 ...
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. ...
Analysis of the Pre-injection Configuration in a Marine Engine Through Several MCDM Techniques
(University of Zagreb Faculty of Mechanical Engineering and Naval Architecture, 2021)
[Abstract] The present manuscript describes a computational model employed to characterize the performance and emissions of a commercial marine diesel engine. This model analyzes several pre-injection parameters, such as ...
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 ...
Analysis of a nature-inspired shape for a vertical axis wind turbine
(MDPI, 2022-07-12)
[Abstract] Wind energy is gaining special interest worldwide due to the necessity of reducing pollutant emissions and employ renewable resources. Traditionally, horizontal axis wind turbines have been employed but certain ...
