A Fractional Derivative Modeling of Heating and Cooling of LED Luminaires
(MDPI, 2020-03)[Abstract] In the context of energy efficient lighting, we present a mathematical study of the heating and cooling processes of a common type of luminaires, consisting of a single light-emitting diode source in thermal ... -
Analysis and Comparison of Spatial–Temporal Entropy Variability of Tehran City Microclimate Based on Climate Change Scenarios
(MDPI, 2019)[Abstract] Urban microclimate patterns can play a great role for the allocation and management of cooling and heating energy sources, urban design and architecture, and urban heat island control. Therefore, the present ... -
Effect of climate change on outdoor termal comfort in humid climates
(Springer, 2014)[Abstract] Background: Galicia, in northwest Spain, experiences warm summers and winters. However, the higher relative humidity that prevails the whole year through and the location of the summer hot points are related ... -
Empowering CO2Eco-Refrigeration With Colossal Breathing-Caloric-Like Effects in MOF-508b
(Wiley, 2024)[Abstract] Today,≈20% of the electric consumption is devoted to refrigeration; while,≈50% of the final energy is dedicated to heating applications. In this scenario,many cooling devices and heat-pumps are transitioning ... -
Energy Efficiency and Environmental Measures for Floating Storage Regasification Units
(Elsevier, 2021-09-30)[Abstract] In view of the need to reduce greenhouse gas emissions from the maritime sector, this paper proposes design and operation indicators for the assessment of Floating Storage Regasification Unit (FSRU) energy ... -
Energy, exergy, economic and environmental analysis of a regasification system integrating simple ORC and LNG open power cycle in floating storage regasification units
(University of Zagreb, Faculty of Mechanical Engineering and Naval Architecture, 2023)[Abstract] A thermodynamic, economic and environmental analysis of a regasification system including a simple Organic Rankine Cycle (ORC) and an Open Organic Rankine Cycle (OC) to utilise the liquefied natural gas (LNG) ... -
Exploitation of Liquefied Natural Gas Cold Energy in Floating Storage Regasification Units
(University of Zagreb, Faculty of Mechanical Engineering and Naval Architecture, 2021)[Abstract] This paper aims to review regasification technology installed in Floating Storage Regasification Units (FSRUs) and the potential offered by the exploitation of cold energy from liquefied natural gas (LNG) in ... -
Fatigue due to on board work conditions in merchant vessels
(Universidad de Catabria, Spanish Society of Maritime Research (SEECMAR), 2020)[Abstract] Several publications point to the human error like the fundamental cause of the practical whole of theaccidents. Inside these accidents, the fatigue has been identified like a recurrent cause, already was asfirst ... -
Generation of H₂ on Board Lng Vessels for Consumption in the Propulsion System
(Sciendo, 2020)[Abstract] At present, LNG vessels without reliquefaction plants consume the BOG (boil-off gas) in their engines and the excess is burned in the gas combustion unit without recovering any of its energy content. Excess BOG ... -
HTR-Based Power Plants’ Performance Analysis Applied on Conventional Combined Cycles
(Hindawi-Wiley, 2015)[Abstract] In high temperature reactors including gas cooled fast reactors and gas turbine modular helium reactors (GT-MHR) specifically designed to operate as power plant heat sources, efficiency enhancement at effective ... -
Novel Modeling for the Calculation of the Center of Lateral Resistance Position of Different Ships Making Use of a Full Mission Bridge Simulator and AI Tools
(MDPI, 2024)[Abstract] Ship maneuvering in ports is increasingly reduced because the increase in ship size is not proportional to the increase in port areas. Furthermore, the number of assisted vessels and the need for tugboats working ... -
On board LNG reliquefaction technology: a comparative study
(Walter de Gruyter, 2014)[Abstract] Reliquefaction technologies are being currently applied on board liquefied natural gas (LNG) carriers on the basis of economic criteria and energy efficiency. A variety of reliquefaction techniques have been ... -
Relevance of Communicative, Team Effectiveness, and Long-Range Planning Skills in Vessel Crewmembers
(Gate Association for Teaching and Education (GATE), 2023)[Abstract] In recent years, soft skills have become increasingly important in many areas of the labor market and in the training of higher education students. This paper explores the perception that different crewmembers ... -
The decarbonisation of the maritime sector: Horizon 2050
(University of Zagreb, Faculty of Mechanical Engineering and Naval Architecture, 2024)[Abstract] The decarbonisation of the maritime sector is one of the world's priorities to reduce the volume of polluting emissions. The basis of this decarbonisation is the adaptation of existing ships to emission control ... -
Thermo-Economic Comparison between Three Different Electrolysis Technologies Powered by a Conventional Organic Rankine Cycle for the Green Hydrogen Production Onboard Liquefied Natural Gas Carriers
(MDPI, 2024)[Abstract] The high demand for natural gas (NG) worldwide has led to an increase in the size of the LNG carrier fleet. However, the heat losses from this type of ship’s engines are not properly managed, nor is the excess ... -
Thermodynamic and Economic Analyses of Zero-Emission Open Loop Offshore Regasification Systems Integrating ORC with Zeotropic Mixtures and LNG Open Power Cycle
(MDPI, 2022)[Abstract] The present study provides an energy, exergy and economic analysis of a seawater regasification system (open loop) combining stages of simple organic Rankine cycles (ORCs) arranged in series with an open organic ... -
Thermodynamic and Environmental Analyses of a Novel Closed Loop Regasification System Integrating ORC and CO2 Capture in Floating Storage Regasification Units
(Elsevier, 2022)[Abstract] Regasification systems in Floating Storage Regasification Units (FSRUs) that use the steam generated by the boilers as the heat source (closed loop) in the liquefied natural gas (LNG) regasification process are ... -
Wind turbines design corrections for next Galicia climatic conditions
(Sharif University of Technology, 2017)[Abstract] Galicia, placed in northwest of Spain, is a clear example of global wind energy development as a consequence of its climate conditions. Despite this fact, previous research works have indicated a climate change ...
