  1. 1. Köldbryggor i ytterväggar i trähus

    Uppsats för yrkesexamina på grundnivå, Linnéuniversitetet/Institutionen för byggteknik (BY)

    Författare :Mouaath Husein; Arsalan Duna; [2024]
    Nyckelord :Linjära köldbryggor; Energiberäkning; Värmemotstånd; Värmegenomgångskoefficient; Genomsnittliga värmegenomgångskoefficient; Träandel; Vip Energy; Termografering;

    Sammanfattning : Thermal bridges are areas of a building where heat is more likely to escape to the outside. They are caused by materials with different thermal conductivities, such as metal, concrete, or timber. Thermal bridges can lead to increased energy consumption, condensation, and structural damage.

  4. 3. Dissolution of Cored Wire in Steel Melt : Optimization of Feeding Rate

    Master-uppsats, KTH/Materialvetenskap

    Författare :Hagen Christian Hagens; [2022]
    Nyckelord :Cored wire injection · light alloy addition · feed rate optimization · inclusions modification · finite difference method;

    Sammanfattning : Calcium treatment is an established operation in the production of steels. Most importantly, it serves to modify detrimental inclusions in the melt for improved castability and superior product properties. Due to calcium’s low melting point and high vapour pressure, its addition to liquid steel is challenging and yields are generally low. LÄS MER

  5. 4. Simulation of solidification and cooling of a casting product using COMSOL Multiphysics

    Master-uppsats, Lunds universitet/Institutionen för energivetenskaper

    Författare :Tom Allen; [2019]
    Nyckelord :Heat transfer; casting; phase change; COMSOL Multiphysics; Technology and Engineering;

    Sammanfattning : In this project, the cooling and solidification processes for a Valmet Foundry product have been simulated in order to shorten the cooling time. The study has also been done in cooperation with RISE Swecast in Jönköping, as a part of finding ways to make casting procedures more energy efficient. LÄS MER

  7. 5. Residual Stresses Induced by Welding in High Performance Steel

    Uppsats för yrkesexamina på avancerad nivå, Luleå tekniska universitet/Byggkonstruktion och brand

    Författare :Rebecca Erlingsdotter Stridsman; Felicia Månsson; [2018]
    Nyckelord :Residual Stresses; High Performance Steel; Heat transfer; Abaqus; Welding;

    Sammanfattning : Today, high performance steel as a construction material is treated as conventional steel in the European standards. Referring to the Eurocodes, the buckling curves for dimensioning of steel constructions only presents values up to steel grade S460, meaning that the full potential of high performance steel is not considered.
