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 ...
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 ...
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 ...
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 ...
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 ...
