Numerical Analysis of NOₓ Reduction Using Ammonia Injection and Comparison With Water Injection
(MDPI, 2020)
[Abstract] This work analyzes NOₓ reduction in a marine diesel engine using ammonia injection directly into the cylinder and compares this procedure with water injection. A numerical model based on the so-called inert ...
Proposal of a Nature-Inspired Shape for a Vertical Axis Wind Turbine and Comparison of Its Performance with a Semicircular Blade Profile
(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 ...
Optimization of a Multiple Injection System in a Marine Diesel Engine through a Multiple-Criteria Decision-Making Approach
(MDPI, 2020)
[Abstract] In this work, a numerical model was developed to analyze the performance and emissions of a marine diesel engine, the Wärtsilä 6L 46. This model was validated using experimental measurements and was employed to ...
NOₓ Reduction in Diesel-Hydrogen Engines Using Different Strategies of Ammonia Injection
(MDPI, 2019-04)
[Abstract] In order to reduce NOₓ emissions in internal combustion engines, the present work analyzes a measurement which consists of injecting ammonia directly into the combustion chamber. A commercial compression ignition ...
Assessment of the Materials Employed in Green Artificial Reefs for the Galician Estuaries in Terms of Circular Economy
(MDPI, 2020)
