  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. Numerical evaluation of the ground vortex

    Master-uppsats, KTH/Teknisk mekanik

    Författare :Martin Babo; [2022]
    Nyckelord :Turbofan engine; CFD; Flow simulation; Ground Vortex; External aerodynamics;

    Sammanfattning : This master thesis covers the realization of a CFD calibration study regarding the numerical simulation of the ground vortex phenomenon. As part of InVIGO project (EU CleanSky2), wind tunnel test campaigns were performed using a nacelle model combined with a movable raised floor. LÄS MER

  4. 3. Design of a High Subsonic Nozzle for a Transonic Linear Cascade Operating at Near Stall Conditions

    Kandidat-uppsats, KTH/Energiteknik

    Författare :César Lucio; [2021]
    Nyckelord :;

    Sammanfattning : This thesis presents the results of computational fluid dynamics (CFD) design calculations of a subsonic nozzle operating at Mach number 0.85 in a transonic linear cascade wind tunnel. The purpose of the nozzle is to accelerate a fluid by decreasing the pressure energy and raising the kinetic one. LÄS MER

  5. 4. Fluid field analysis on a flexible combustor for a hybrid Solar / Brayton system : A numerical study

    Master-uppsats, KTH/Skolan för industriell teknik och management (ITM)

    Författare :PAUL JACQUEMARD; [2020]
    Nyckelord :CFD; MGT; LPP Combustor; Impinging hole; CFD; MGT; LPP-brännare; slaghålsvägg;

    Sammanfattning : Recent improvements to concentrating solar dish systems lead to further focus on hybridization systems for small-scale power generation applications. Variability of the solar load creates new requirements for combustion systems. LÄS MER

  7. 5. OPTIMIZATION OF NOZZLE SETTINGS FOR A FIGHTER AIRCRAFT

    Master-uppsats, Mälardalens högskola/Industriell ekonomi och organisation

    Författare :Alexander Stenebrant; Nor Al-Mosawi; [2019]
    Nyckelord :Low-bypass turbofan; afterburner; convergent-divergent nozzle; afterbody drag; computational fluid dynamics.;

    Sammanfattning : Most fighters use the convergent-divergent nozzle configuration to accelerate into the supersonic realm. This nozzle configuration greatly increases the thrust potential of the aircraft compared to the simpler convergent nozzle. LÄS MER
