On the analytic explanation of experiments where turbulence vanishes in pipe flow
(Cambridge University Press, 2022-11-02)[Abstract]: The present research will provide an analytical explanation to experiments destabilising turbulence in pipe flow reported in Kuehnen et al. (Nat. Phys., vol. 14, 2018, 386–390). Those experiments show four ... -
Opening or Not Opening Educational Centers in Time of SARS-CoV-2? Analysis of the Situation in Galicia (Spain)
(MDPI, 2022-05-05)[Abstract] The appearance of the SARS-CoV-2 pandemic on the world stage has implemented changes in all social activities and, therefore, in teaching at all educational levels. On the one hand, it is argued that the closure ... -
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 ... -
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. ... -
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 ... -
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 ... -
Proposed Conceptual Framework to Design Artificial Reefs Based on Particular Ecosystem Ecology Traits
(MDPI, 2022-04-28)[Abstract] Overfishing and pollution have led to marine habitat degradation, and as a result, marine fisheries are now in decline. Consequently, there is a real need to enhance marine ecosystems while halting the decline ... -
Revising Concepts on Liquid–Liquid Extraction: Data Treatment and Data Reliability
(ACS Publications, 2022)[Abstract] The intention of this article is to clarify some concepts and relevant aspects of the experimental determination and treatment of liquid–liquid equilibrium data for ternary systems. Distinction is made between ... -
Selection of an Appropriate Pre-Injection Pattern in a Marine Diesel Engine Through a Multiple-Criteria Decision Making Approach
(MDPI, 2020-04-04)[Abstract] In the present work, a numerical model was developed to analyze a commercial diesel engine. The adequacy of this model was validated using experimental results. This model was employed to study several pre-injection ... -
Self-Diffusion in Nanofluids of Nonelongated Particles in the Dilute Limit
(Springer, 2021-07)[Abstract] The dynamic features of a dilute suspension of nanoparticles (nanofuid) are fully modifed depending on the dominant particles slip mechanism acting in the suspension. Self-difusion efects in highly sheared diluted ... -
Simulation of Boiling Heat Transfer at Different Reduced Temperatures with an Improved Pseudopotential Lattice Boltzmann Method
(MDPI, 2020-07)[Abstract] The pseudopotential Lattice Boltzmann Method has attracted much attention in the recent years for the simulation of boiling heat transfer. Many studies have been published recently for the simulation of the ... -
