  1. 21. A Numerical Study of Melt Pool Heat Transfer in the IVR of a PWR

    University essay from KTH/Fysik

    Author : Yuer Zhao; [2021]
    Keywords : In-vessel melt retention; corium pool; Zr oxidation ratio; melt pool convection; CFD; SST k-ω turbulence model; Smältretention i kärlet; koriumpöl; Zr-oxidationsförhållande; konvektion i en smältpöl; CFD; SST k-ω turbulensmodell;

    Abstract : This thesis aims to provide the thermal condition of melt pool convection by CFD simulation, which is important to the assessment of the invessel melt retention (IVR) strategy widely adopted in Generation III pressurized water reactors (PWRs). As a severe accident mitigation measure, the IVR strategy is realized through external cooling of the lower head of a reactor pressure vessel (RPV). READ MORE

  2. 22. Integration of solar thermal collectors in the dairy industry: A techno-economic assessment : A case study of Dubai

    University essay from Uppsala universitet/Institutionen för elektroteknik

    Author : Hassim Shah; [2021]
    Keywords : Solar thermal; parabolic trough collector; levelized cost of heat; integration schemes;

    Abstract : A predominant amount of energy needed in the industrial sector is in the form of heat. A significant number of industries in the world still relies on fossil fuels for meeting their heat requirements. READ MORE

  3. 23. Rooftop plant factories: effects on energy use for heating, cooling and electric lighting

    University essay from Lunds universitet/Avdelningen för Energi och byggnadsdesign; Lunds universitet/Institutionen för arkitektur och byggd miljö

    Author : Yizhi Zhang; [2021]
    Keywords : Urban and peri-urban agriculture and forestry UPAF ; urban farming UF ; rooftop greenhouse RTG ; lighting; daylighting; energy conservation; roof; greenhouse; food; cities.; Technology and Engineering;

    Abstract : Within the next thirty years, two thirds of the human population will live in a city. This growing urban population requires a major shift in the way we produce and distribute food, since industrial agriculture practices contribute to climate change, biodiversity losses, pollution of waterways, soil degradation, etc. READ MORE

  4. 24. Multidimensional Assessment For a Case Studied Zero Energy Building : Climate positive buildings with and without a connection to the district heating network

    University essay from Mälardalens högskola/Akademin för ekonomi, samhälle och teknik

    Author : Daniel Rimec; [2021]
    Keywords : CO2-mitigation; Zero-energy building; Climate positive buildings; ETC buildings; Enviro-economic; District heating network; ground source heat pump;

    Abstract : The purpose of this report is to get an overview of the CO2 reduction possibilities when adopting different renewable energy source, when the case studied building sustains a district heating network connection and when not, and how the renewable energy source flexibilities (Solar and Wind) differ depending on region. The method regards a ETC house that falls into the climate positive category and assesses the reduction when comparing CO2 emissions form the energy demand. READ MORE

  5. 25. The carbon footprint caused by the oversizing of building service systems : A case study of an NHS Hospital

    University essay from KTH/Hållbar utveckling, miljövetenskap och teknik

    Author : Maria Hein; [2020]
    Keywords : Design; dimensioning; heating; cooling; boiler; chiller; pump; energy performance; environmental impact; mitigation strategy;

    Abstract : Energy usage in buildings is a main contributor to CO2 emissions and in order for the EU to reach the 2050 goal of carbon-neutrality, there is a great need to improve the energy efficiency in buildings, particularly commercial buildings that often are substantially overdesigned. Excess margins in the design process of building services result in an oversizing of these systems which has great environmental impacts, divided up as the operational and embodied carbon footprints.
