Proposal of a Nature-Inspired Shape for a Vertical Axis Wind Turbine and Comparison of Its Performance with a Semicircular Blade Profile

Blanco, Javier; Rodríguez-García, JuanDeDios; Couce-Casanova, Antonio; Lamas, M.I. (MDPI, 2021)

[Abstract] In order to improve the efficiency of the Savonius type vertical axis wind turbine, the present work analyzes an improvement based on an innovative rotor geometry. The rotor blades are inspired on an organic ...

Analysis of the Pre-Injection System of a Marine Diesel Engine Through Multiple-Criteria Decision-Making and Artificial Neural Networks

Rodríguez, C.G.; Lamas, M.I.; Rodríguez-García, JuanDeDios; Abbas, A. (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 the Pre-injection Configuration in a Marine Engine Through Several MCDM Techniques

Rodríguez, Carlos G.; Lamas, M.I.; Rodríguez-García, JuanDeDios; Caccia, Claudio (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

Rodríguez, Carlos G.; Lamas, M.I.; Rodríguez-García, JuanDeDios; Abbas, Amr (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 ...
