  1. 6. CFD Results Used in the Design Process of the SEFACE Facility : KTH Master's Thesis Report

    Master-uppsats, KTH/Kärnenergiteknik

    Författare :Nathaniel Torkelson; [2022]
    Nyckelord :CFD; liquid lead corrosion; flow accelerated corrosion erosion; SEFACE; SUNRISE; ANSYS CFX; CFD; flytande blykorrosion; flödesaccelererad korrosionserosion; SEFACE; SUNRISE; ANSYS CFX;

    Sammanfattning : This project uses CFD analysis to make design choices for a facility to test flow accelerated lead corrosion erosion of steel samples. Two conceptual designs are considered and compared through mechanical and physical criteria. The first design uses steel samples on stationary plates next to rotating discs. LÄS MER

  3. 7. Optimering av Savoniusturbinens effektivitet i marina strömmar med hjälp av CFD-analys av flödesriktare

    Kandidat-uppsats, Uppsala universitet/Elektricitetslära

    Författare :Leonard Hammar; Jacob Kovaleff Malmenstedt; [2022]
    Nyckelord :MCT; Marine Current Turbine; Savonius turbine; CFD; Ansys fluent; diffuser augmented turbine; Savoniusturbin; Marina strömmar; CFD; Ansys fluent; flödesriktare;

    Sammanfattning : The Savonius turbine is a self-starting vertical axis turbine that has a few advantages compared to other vertical axis turbines such as lower cost, lower noise and is relatively easy to manufacture. This turbine does however have a lower efficiency and is therefore less used in the electricity production than other turbines. LÄS MER

  4. 8. Vidareutveckling av brännarenhet till biogasfackla

    M1-uppsats, Karlstads universitet/Avdelningen för maskin- och materialteknik

    Författare :Johansson Magnus; Mohammad Karoum; [2022]
    Nyckelord :Biogas; metan; biogasfackla; fackla; brännare;

    Sammanfattning : This thesis in mechanical engineering has been conducted in collaboration with Camatec Industriteknik AB, to find new concepts for the burner of biogas flares from Biogas Systems AB. Biogas flares are needed to burn off surplus volumes that arise for various reasons during the extraction of biogas.

  5. 9. CFD Analysis of the Flow Into a Preheater

    Master-uppsats, KTH/Teknisk mekanik

    Författare :Eric Axtelius; [2022]
    Nyckelord :Mechanics; Fluid Mechanics; CFD; Preheater; Moisture Separator; Nuclear; Steam; Heat Transfer;

    Sammanfattning : This project has investigated and formed a basis for the thermal- and flow-induceddynamic loads in the lower parts of a preheater situated in a nuclear power plant.Special attention has been given to the bottom plate that separates the heated andnon-heated secondary steam.

  7. 10. CFD Analysis of Water Replenishment Holes in an Offshore Wind Turbine Foundation

    Master-uppsats, Linköpings universitet/Mekanisk värmeteori och strömningslära

    Författare :Shubham Arvind Tupkar; Swetha Sappe Narasimhamurthy; [2022]
    Nyckelord :CFD; Wave Dynamics; Implicit LES; GABC; OpenFOAM; Stokes V; Monopile Foundation; Replenishment Holes;

    Sammanfattning : The study presented in this thesis investigates the passive exchange of enclosed water with seawater in an offshore wind turbine foundation. This thesis was undertaken in collaboration with Vattenfall R&D, Älvkarleby, Sweden. The water exchange is studied by utilizing Computational Fluid Dynamics (CFD) simulations. LÄS MER
