  1. 1. Numerical modelling for characterization of the granular flows impact on the gas flow in a packed-bed-reactor

    University essay from Luleå tekniska universitet/Institutionen för teknikvetenskap och matematik

    Author : Anton Sundström; [2020]
    Keywords : DEM; Discrete element method;

    Abstract : The goal of the project was to characterize the granular flows impact on the gas flow in a packed-bed-reactor. The study was created at Swerim as a master's thesis for Luleå University of Technology. The packed-bed-reactor geometry used in this study is a scaled down blast furnace model. READ MORE

  2. 2. Numerical Study on Air Demand of Free Surface Flows in a Discharge Tunnel

    University essay from Uppsala universitet/Institutionen för fysik och astronomi; Uppsala universitet/Institutionen för fysik och astronomi

    Author : Jonathan Barassa; Rickard Nordlöf; [2020]
    Keywords : Computational Fluid mechanics; Hydropower; Air demand; Free surface flows; ANSYS Fluent;

    Abstract : Aeration issued through a ventilation shaft is an important measure to prevent cavitation and large gauge pressure in flood discharge tunnels. In order to dimension the ventilation shaft appropriately, itis necessary to have a good understanding of the air-water flow in the tunnel. READ MORE

  3. 3. Dimensioning of a cutter wheel bearings

    University essay from Karlstads universitet/Institutionen för ingenjörsvetenskap och fysik (from 2013)

    Author : Kebin Xie; [2020]
    Keywords : cutter wheel; bearing; wear; scuffing; Archard equation; lubrication number; Reynold equation; Hertzian contact theory; impact load factor; FE model; Ansys; contact pressure on bearing;

    Abstract : Mobile Miner 40V is a machine used for rock excavation and developed by Epiroc. This machine is equipped with a large cutter wheel to perform the excavation. After a test run, some surfaces associated with bearings within the cutter wheel were found to be damaged due to scuffing - severe sliding wear. READ MORE

  4. 4. Finite element modelling of LV transformer winding to simulate dynamic events occurring under short circuit : In Ansys Mechanical

    University essay from Blekinge Tekniska Högskola/Institutionen för maskinteknik

    Author : Madhu Venkata Sri Prudhvi Bikkina; [2020]
    Keywords : Ansys Mechanical; LV winding; Power Transformer; Short-circuit; Spiraling; Torsional Mode Shapes;

    Abstract : The ability to withstand a short circuit is the most essential feature of a power transformer. The most important reason to design short-circuits proof transformers is to ensure the reliability of the power grid (avoiding black outs etc.) and safety (fire and explosion in case of failure).

  5. 5. Improved methodology for postulated fuel handling accident

    University essay from Lunds universitet/Institutionen för byggvetenskaper; Lunds universitet/Hållfasthetslära

    Author : Max Fagerberg; [2020]
    Keywords : ANSYS LS-DYNA; FEM; nuclear fuel; solid mechanics; Technology and Engineering;

    Abstract : This report presents a suggestion of an improved method for evaluation of a fuel handling accidents. Using a 3D FE-model and ANSYS LS-DYNA EXT the structural analysis is carried out. Importing geometry from SpaceClaim and simplifying it creates the geometry used in this analysis. READ MORE
