  1. 1. Construction and Evaluation of a Numerical Model for Heat Transfer in a Ladle During Pre-heating : A Finite Volume Approach to the Diffusion Equation using Julia

    University essay from KTH/Materialvetenskap

    Author : Gustaf Bjurstam; [2023]
    Keywords : Finite Volume Method; FVM; Diffusion equation; Ladle; Pre-heating; Baking; Heat equation; Heat transfer; Finita Volymmetoden; FVM; Diffusionsekvationen; Skänk; Förvärmning; Värmeledningsekvationen; Värmeledning;

    Abstract : Heat transfer is key to understanding many processes in engineering. At a steel mill heat transfer is absolutely crucial to understanding most of the processes. One such a process is the pre-heating of a freshly relined ladle. READ MORE

  3. 2. Some Like It Hot: Pre-heating Prior to Bioreactor Treatment Enhances Nitrogen Removal From Mine Drainage

    University essay from Uppsala universitet/Luft-, vatten- och landskapslära

    Author : Laura Nina Bettoni; [2022]
    Keywords : denitrification; nitrate removal; temperature; woodchip bioreactor; waste rock leachate;

    Abstract : Ammonium-nitrate based explosives (NH4NO3) used within the operations of Kiruna iron ore mine release nitrate (NO3-) into the environment, potentially having adverse effects on local river-systems. One way of reducing NO3- impacts to the environment is through a woodchip denitrifying bioreactor (DBR). READ MORE

  4. 3. Investigation on the Optimization of GaN Etching for FinFET Applications

    University essay from Lunds universitet/Institutionen för elektro- och informationsteknik

    Author : Albert Malmros; [2022]
    Keywords : Technology and Engineering;

    Abstract : In the framework of this thesis, the optimization of the etching process of GaN for FinFET applications has been investigated. FinFETs are transistors with a vertical architecture in the shape of fins. These fins are fabricated by etching a pattern into a GaN substrate. The etching is carried out in two steps, a dry etch and a wet etch. READ MORE

  5. 4. Numerical modelling of calcination of limestone : An evaluation of existing calcination model

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

    Author : Marcus Svensson; [2021]
    Keywords : Simulation; Modelling; Numerical; Shrinking core model; Calcination; Limestone;

    Abstract : Calcination is important for modern society as we know it since products from the reaction is used inseveral industries. Calcination is a chemical reaction where a solid particle, e.g., limestone, is exposedto high temperature which causes volatile impurities to be released from the particle. READ MORE

  6. 5. Mechanical properties of compression moulded fibre composite sheets

    University essay from KTH/Hållfasthetslära

    Author : Jakob Engström; [2021]
    Keywords : ;

    Abstract : This master thesis project was carried out at a large international company in the forest industry. The company is currently interested in producing sheet formed composite materials with high wood fibre content that can be further processed and formed using conventional compression moulding.
