  1. 1. Forest growth under future climate change in the context of bioenergy – case studies of combined heat and power plants in Sweden

    Master-uppsats, Lunds universitet/Institutionen för naturgeografi och ekosystemvetenskap

    Författare :Chi Yuen Hui; [2023]
    Nyckelord :Physical Geography; Climate Change; Ecosystem Modelling; LPJ-GUESS; BECCS; Geomatics; Earth and Environmental Sciences;

    Sammanfattning : The pressure to achieve net-zero emissions has pushed for new technologies including carbon capture and storage (CCS) based on the combustion of biomass (BECCS). While bioenergy is a relatively mature industry in Sweden, the addition of CCS may increase the demand for local biomass. LÄS MER

  4. 3. Microstructural, Mechanical and Tribological Studies of Ti-6Al-4V Thin Plates Produced by EBM Process

    Magister-uppsats, Högskolan Dalarna/Materialteknik

    Författare :Onimisi Calistus Sanni; [2019]
    Nyckelord :Additive manufacturing AM ; Electron beam melting EBM ; Mechanical properties; Tribological behaviour; Microhardness; Micro tensile; Thin sections; Ti-6Al-4V;

    Sammanfattning : The titanium alloy, Ti-6Al-4V, is vastly studied and used in many applications because it has a transformation microstructure, which can be tailored for apt properties that are consistent up to 500°C. Compared to conventional steels, this alloy favours certain applications due to its high specific strength, hardenability, corrosion resistance, biocompatibility and weldability. LÄS MER

  5. 4. Thermal Analysis of a Sea Wave Generator

    Master-uppsats, KTH/Elkraftteknik

    Författare :Ezequiel Quijada; [2017]
    Nyckelord :sea wave power generator; magnet overheating; demagnetization; heat transfer; conjugate heat transfer; thermal resistance; Comsol Multiphysics; cooling technique;

    Sammanfattning : Wave power has been increasing the interest of many researchers looking for alternative sustainable energy sources since the reserves have proved to be capable of satisfying a considerable percentage of the world´s energy demands. This option has not been adopted as a sustainable source since there are some challenges in the process of designing a low cost device that converts the kinetic energy of the waves into electric energy and that could still be efficient enough to be competitive against other options.

  7. 5. Thermoplasticity in topology optimization based on finite strain

    Uppsats för yrkesexamina på avancerad nivå, Lunds universitet/Hållfasthetslära

    Författare :Anders Engström; [2017]
    Nyckelord :FEM; topology optimization; finite deformations; thermoplasticity; Technology and Engineering;

    Sammanfattning : A thermoplastic finite strain model is used to model heat generation due to plastic work. Isotropic hardening is used, where the mechanical dissipation acts as heat source in the heat equation. The multiplicative split of the deformation gradient makes it possible to separate plastic and elastic effects. LÄS MER
