  1. 11. Fuktsäkerhet i ventilerade parallelltak

    Uppsats för yrkesexamina på avancerad nivå, Lunds universitet/Avdelningen för Byggnadsfysik

    Författare :Gabriel Odén; Gustav Månhardt; [2020]
    Nyckelord :Parallelltak; WUFI; blinda beräkningar; varierad luftomsättning; luftflödesmodell; fuktsäkerhet; MRD; termisk drivkraft; klimatdata; ventilerad luftspalt; värme och fukttransport; konvektion; analytisk lösning; fallstudie; Technology and Engineering;

    Sammanfattning : Parallel roofs are commonly used in Sweden when constructing new small house buildings and are also difficult to access for inspection. Furthermore, high demands are set in the Swedish building regulations, although there are no clear guidelines for their compliance. LÄS MER

  3. 12. Temperature distribution in air tight cavities of steel framed modular buildings when exposed to fire

    Uppsats för yrkesexamina på grundnivå, Luleå tekniska universitet/Institutionen för samhällsbyggnad och naturresurser

    Författare :Elin Bergroth; Greta Torstensson; [2019]
    Nyckelord :Cavities; fire furnace; fire test; modular building; steel; TASEF; Brandugn; brandtest; hålrum; modulbyggnader; stål; TASEF;

    Sammanfattning : A common way to construct large buildings is by assemble prefabricated modules around a load bearing steel construction. However, if a fire occurs these buildings can be subject to a rapid fire spread due to its cellular nature. LÄS MER

  4. 13. Solcellers effektivitet vid integrerat eller applicerat montage

    Master-uppsats, Karlstads universitet/Avdelningen för energi-, miljö- och byggteknik

    Nyckelord :BIPV; air cavity; naturally convection; BIPV; luftspalt; skorstenseffekten; naturlig konvektion;

    Sammanfattning : Sweden has a climate target to get a total renewable electricity production by 2040, in order to succeed with the goal, the proportion of solar energy needs to increase. Increased environmental awareness and increased profitability of solar cells have led to an increase. LÄS MER

  5. 14. Thermal Loads in Space Turbines

    Master-uppsats, Luleå tekniska universitet/Rymdteknik

    Författare :Emily Chen; [2019]
    Nyckelord :;

    Sammanfattning : Prediction of thermal loads within cavities in space turbine, has as been a challenging task  in aspects of achieving accurate and reasonable estimations that are crucial for design concepts. The difficulty lies within the turbulent flow and its thermal interaction with the structure inside such section. LÄS MER

  7. 15. Design optimization for obtaining zero defects in steel casting

    Master-uppsats, Högskolan i Jönköping/JTH, Material och tillverkning

    Författare :Pranit Pramod Purkar; [2019]
    Nyckelord :Casting; Defects; Gating System; Molten Metal; Mould; Simulation;

    Sammanfattning : This thesis is about the design of the gating system and selection of proper alloy for defects free (grate bar) casting. The gating system plays an important role in casting manufacturing process. The gating system has different elements like pouring cup, sprue, well, runner, riser, and ingates. LÄS MER
