  1. 1. Numerical Simulations of Metal Recovery for Battery Recycling

    Master-uppsats, KTH/Processteknologi

    Författare :Morgan Ölander; [2023]
    Nyckelord :Batteriåtervinning; Metall återvinning; Kristallisation; Computational Fluid Dynamics CFD ; Populationsbalansmodellering; Battery recycling; Metal recovery; Crystallisation; Computational Fluid Dynamics CFD ; Population balance modelling;

    Sammanfattning : Den pågående elektrifieringen av transport och samhälle kräver utveckling av nya metoder för återvinning av batterier. Hydrometallurgi som fokuserar på selektiv kristallisation av metaller är ett intressant alternativ för dessa ändamål. Dessa system kan studeras genom modellering och simulering. LÄS MER

  3. 2. Influence of Reynolds Number and Heat Flux when Cooling an Array of Cylinders

    Master-uppsats, Luleå tekniska universitet/Institutionen för system- och rymdteknik

    Författare :Erik Fagerström; [2020]
    Nyckelord :Reynolds Number; Heat Flux; Porous Media; Cooling;

    Sammanfattning : When batteries are used, it is of interest to know how high the temperature will become and if the cooling is efficient enough. In this thesis project, the geometry used are batteries placed in an array shape, inside a box. This gives the possibility of assuming porosity conditions when looking at the box from the outside.

  4. 3. Interscale transport of Reynolds stresses in wall-bounded flows

    Master-uppsats, KTH/Skolan för teknikvetenskap (SCI)

    Författare :Gioele Ferrante; Andres Morfin; [2019]
    Nyckelord :Reynolds Stress; Zero-Pressure Gradient Turbulent Boundary Layer; Turbulent Couette Flow; Inverse Interscale Transport; Energy Cascase; Wall-bounded Flows; Direct Numerical Simulation; Large Eddy Simulation.;

    Sammanfattning : Couette, pipe, channel, and zero-pressure gradient (ZPG) turbulent boundary layer (TBL) flows have classically been considered as canonical wall-bounded turbulent flows since their near-wall behavior is generally considered to be universal, i.e. invariant of the flow case and the Reynolds number.

  5. 4. Numerical simulations of mixing for gas exhaust treatment

    Master-uppsats, KTH/Strömningsmekanik och Teknisk Akustik

    Författare :Viktor Lahti; [2019]
    Nyckelord :;

    Sammanfattning : According to the World Health Organisation, nine out of ten people live in places with sub par air quality. Therefore, the study of the treatment of polluted air is from a global point of view of great importance, and a matter of life quality for both humans and as well as animals. LÄS MER

  7. 5. Source Term Estimation in the Atmospheric Boundary Layer : Using the adjoint of the Reynolds Averaged Scalar Transport equation

    Master-uppsats, Umeå universitet/Institutionen för fysik

    Författare :Brännvall Tobias; [2015]
    Nyckelord :CFD; Source; Source term; STE; RANS; k epsilon; Adjoint; Adjoint equation; Reynolds transport equation; transport equation; adjoint of transport equation; Adjoint duality;

    Sammanfattning : This work evaluates whether the branch of Reynolds Averaging in Computational Fluid Dynamics can be used to, based on real field measurements, find the source of the measured gas in question. The method to do this is via the adjoint to the Reynolds Averaged Scalar Transport equation, explained and derived herein. LÄS MER
