  1. 1. Modelling the Occurrence and Fate of Microplastics Caused by Tyre Wear on Highway E18

    Master-uppsats, Uppsala universitet/Luft-, vatten- och landskapslära

    Författare :Aniruddha Kshirsagar; [2023]
    Nyckelord :Tyre Wear Plastics; stormwater system; Microplastics; settling; hetero-aggregation; modelling; Modellering; mikroplaster;

    Sammanfattning : The accumulation of microplastics (MPs) are a growing concern for the environment, the maximum contributor to the MP pollution is tyre wear particles or TWPs. TWPs can accumulate in the environment and remain there for long periods of time and hence have the ability to disrupt ecosystems. LÄS MER

  3. 2. Verification and validation of the implementation of an Algebraic Reynolds-Stress Model for stratified boundary layers

    Master-uppsats, KTH/Teknisk mekanik

    Författare :Martina Formichetti; [2022]
    Nyckelord :Atmospheric boundary layer; turbulence modelling; stratified flows; eddy viscosity; eddy diffusivity;

    Sammanfattning : This thesis studies the implementation of an Explicit Algebraic Reynolds-Stress Model(EARSM) for Atmospheric Boundary Layer (ABL) in an open source ComputationalFluid Dynamics (CFD) software, OpenFOAM, following the guidance provided by thewind company ENERCON that aims to make use of this novel model to improvesites’ wind-field predictions. After carefully implementing the model in OpenFOAM,the EARSM implementation is verified and validated by testing it with a stratifiedCouette flow case. LÄS MER

  4. 3. Modelling the Nordic Hydro Power System with Spine Toolbox

    Master-uppsats, KTH/Skolan för elektroteknik och datavetenskap (EECS)

    Författare :Angelica Waernlund; [2021]
    Nyckelord :;

    Sammanfattning : In the Nordic power system, the largest balancing resource is hydro power. For future developments of the Nordic power system with more renewable and varying energy, such as wind power, the hydro power and its limitations must thus be taken into account. To be able to study this, a model with these limitations is needed. LÄS MER

  5. 4. Mathematical modelling of Degussa Furnace

    Kandidat-uppsats, KTH/Materialvetenskap

    Författare :Rans Faraydoun Muhammed; [2021]
    Nyckelord :Furnace; CFD; ANSYS; Thermodynamic model; Exchange time; Ugn; CFD; ANSYS; Termodynamisk model; Utbytestid;

    Sammanfattning : The energy demands in the world is rapidly increasing and with this,  a supply nuclear  power  is  of  much  interest.    Nuclear  fuel  is  relatively  efficient  when comparing to power sources like wind­ and hydropower plants. LÄS MER

  7. 5. Open Source Model of the Nordic Power System for EU Project Spine

    Master-uppsats, KTH/Skolan för elektroteknik och datavetenskap (EECS)

    Författare :Aravind Satheeskumar; [2020]
    Nyckelord :Nordic Power System; power system modelling; power flow analysis; optimisation; transmission line parameter estimation; Nordic Power System; modellering av kraftsystem; effektflödesanalys; optimering; uppskattning av transmissionslinje-parametrar;

    Sammanfattning : Decision problems in operation and planning of power systems often rely on large-scale models and data sets. Lack of historical power flow data due to regulatory restrictions often limits researchers to study the system with aggregated network models. LÄS MER
