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

    University essay from Lunds universitet/Institutionen för naturgeografi och ekosystemvetenskap

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

    Abstract : 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. READ MORE

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

    University essay from Högskolan Dalarna/Materialteknik

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

    Abstract : 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. READ MORE

  4. 3. Thermal Analysis of a Sea Wave Generator

    University essay from KTH/Elkraftteknik

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

    Abstract : 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.

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

    University essay from Lunds universitet/Hållfasthetslära

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

    Abstract : 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. READ MORE

  6. 5. Chimney Effect in Data Centers : On the possibility to achieve natural draft through servers

    University essay from Umeå universitet/Institutionen för tillämpad fysik och elektronik

    Author : Sebastian Fredriksson; [2017]
    Keywords : ;

    Abstract : Data centers has in recent years experienced a rapid growth in numbers and size. Essentially, data centers are facilities housing IT equipment such as servers, switches and other network devices which use large amounts of electrical energy. Electrical energy is converted to heat by the data processing units in servers and therefore demand cooling. READ MORE
