  1. 1. Wall-Resolved and Wall-Modelled LES for a NACA4412 Wing Profile in OpenFOAM

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

    Författare :Nikolaos Charisoudis; [2024]
    Nyckelord :;

    Sammanfattning : The purpose of this study is to perform computational fluid dynamics (CFD) simulationfor an incompressible flow around an airfoil and investigate the aerodynamicproperties for different Reynolds numbers (400, 000 and 1, 000, 000) based on the chordlength, at the moderate angle of attack (AoA) of 5o . For this purpose a detailedevaluation of wall-resolved and wall-modelled large-eddy simulations (LES) wereconducted for the NACA4412 wing profile. LÄS MER

  3. 2. En fallstudie om Sverigedemorkaternas förändring mellan 1999-2018

    L2-uppsats, Lunds universitet/Statsvetenskapliga institutionen

    Författare :Oscar Wall; Henrik Svensson; [2022]
    Nyckelord :Law and Political Science;

    Sammanfattning : Our purpose of this essay is to study the Swedish political party Sverigedemokraterna. We will examine the change or development during the last twenty years. During this time, the party has grown massively both in size but also in regards of influence on the political agenda. LÄS MER

  4. 3. Makt, migration och människor, en studie om högerpopulismens hårda grepp om en allt svagare liberal demokrati

    Kandidat-uppsats, Lunds universitet/Statsvetenskapliga institutionen

    Författare :Ebba Behre; [2021]
    Nyckelord :Donald Trump; right-wingpopulism; migration policy; immigrant discourse; politics of Walls; border; critical discourse theory; Law and Political Science;

    Sammanfattning : This thesis aims to bring a greater understanding of the normalization of right-wing populism by analysing the immigration discourse of Donald Trump and the way he speaks about building the Wall against Mexico. In this study, three different transcripts of his speeches are analysed with a critical discourse theory and the right- wing theoretical framework of Ruth Wodak. LÄS MER

  5. 4. Design- och simuleringsstudie av flödeshus och sensorkropp

    M1-uppsats, KTH/Hållbar produktionsutveckling (ML)

    Författare :Klara Larsson Sparr; Mathias Muhonen; [2020]
    Nyckelord :Flow measurement; CFD; construction; product development; fluid mechanics; simulation study; pitot tube; design; streamline shape; wing profile; cavitation; pressure measurement; CAD; solid modelling; Flödesmätning; simulering; CFD; strömningsmekanik; pitotrör; design; produktutveckling; strömlinjeform; vingprofil; kavitation; tryckmätning; CAD; solidmodellering;

    Sammanfattning : I detta arbete har ett koncept utvecklats för en flödesmätningsmetod med en intern sensorkropp samt bibehållen flödeshastighet. Denna mätmetod består av en sensorkropp i ett flödeshus där mätningen av flödet utförs med hjälp av pitotrörsberäkningar. LÄS MER

  7. 5. Enabling high-fidelity measurements of turbulent boundary layer flow over wing sections in the MTL wind tunnel.

    Master-uppsats, KTH/Mekanik

    Författare :Fermin Mallor; [2019]
    Nyckelord :Fluid mechanics; aerodynamics; turbulence; RANS; wind-tunnel experiments; insert design; Strömningsmekanik; aerodynamik; turbulens; RANS; vindtunnel experiment; inlaga designen;

    Sammanfattning : A reinforced fiber-glass model of a NACA 4412 wing profile is designed and set-up in the Minimum Turbulence Level (MTL) wind tunnel facility at KTH. The model has 65 pressure taps orifices, and the set-up includes two mounting panels designed to allow for particle image velocimetry (PIV) and hot wire anemometry (HWA) measurements of the boundary layer (to be performed in a future campaign).
