Numerical Model to Analyze the Physicochemical Mechanisms Involved in CO₂ Absorption by an Aqueous Ammonia Droplet
(MDPI, 2021-04)
[Abstract] CO₂ is the main anthropogenic greenhouse gas and its reduction plays a decisive role in reducing global climate change. As a CO₂ elimination method, the present work is based on chemical absorption using aqueous ...
Effect of multiple injection strategies on emissions and performance in the Wärtsilä 6L 46 marine engine. A numerical approach
(Elsevier, 2019-01-01)
[Abstract] The present paper proposes a Computational Fluid Dynamics model to analyze the operation cycle and exhaust gas composition in a four-stroke marine diesel engine, the Wärtsilä 6L 46. Once validated, the numerical ...
Numerical Model of SO2 Scrubbing with Seawater Applied to Marine Engines
(Sciendo, 2016-06-30)
[Abstract]: The present paper proposes a CFD model to study sulphur dioxide (SO2) absorption in seawater. The focus is on the treatment of marine diesel engine exhaust gas. Both seawater and distilled water were compared ...
Numerical Analysis of Emissions from Marine Engines Using Alternative Fuels
(Sciendo, 2015-12-30)
[Abstract]: The current restrictions on emissions from marine engines, particularly sulphur oxides (SOx ), nitrogen oxides (NOx ) and carbon dioxide (CO2 ), are compelling the shipping industry to a change of tendency. In ...
Numerical analysis of several port configurations in the Fairbanks-Morse 38D8-1/8 opposed piston marine engine
(University of Zagreb. Faculty of Mechanical Engineering and Naval Architecture, 2015)
[Abstract] The aim of the present paper is to analyze several port configurations in the Fairbanks-Morse 38D8-1/8 marine diesel engine. The motivation comes from the high number of intake and exhaust ports which characterizes ...
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 ...
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 ...
