  1. 1. Statistical Analysis on Aerodynamics of Passenger Vehicles

    University essay from Uppsala universitet/Sannolikhetsteori och kombinatorik

    Author : Dingkang Peng; [2023]
    Keywords : statistics; aerodynamics; automotive engineering; causality; time series; cluster analysis;

    Abstract : This thesis aims to use statistical methods to analyze wind tunnel data generated in automotive aerodynamics testing to understand the properties of aerodynamic force and pressure in a vehicle's working environment. The data used for analysis are visualized, clustered and finally analyzed for Granger causality to see whether a causal link exists between different variables. READ MORE

  3. 2. Forced response numerical investigation of a transonic compressor rotor

    University essay from KTH/Skolan för industriell teknik och management (ITM)

    Author : Mariana Pires Gonçalves Toco Dias; [2023]
    Keywords : Compressor; rotor; blisk; aeroelasticity; aerodynamic damping; CFD; transient; forced response;

    Abstract : The present thesis discusses the forced response of a rotor’s bladed-disk when excited by the periodic force produced by a wake generator, or Inlet Guide Vane (IGV),with 8 equally-spaced blades. These components are part of an axial transonic compressor rig, moreover the Transonic Compressor Darmstadt 1 (TCD1), located at the Technical University of Darmstadt. READ MORE

  4. 3. Investigation of a Novel Atmosphere-Breathing Electric Propulsion Platform and Intake

    University essay from KTH/Skolan för elektroteknik och datavetenskap (EECS)

    Author : Kun Feng; [2023]
    Keywords : ABEP; VLEO; DSMC; FMF; Orbital Aerodynamics; ABEP; DSMC; VLEO; FMF; Orbital Aerodynamics;

    Abstract : Very Low Earth Orbit (VLEO) provides many benefits for space missions, including better image resolution for Earth observation, better telecommunication link with ground stations, lower launch cost, lower risk of collisions, and fast end-of-life disposal. The last point in benefit is also the main challenge for placing satellites in VLEO. READ MORE

  5. 4. Design and construction of an access concept for a tow bar mounted cargo box : Analysis and development of the user experience

    University essay from KTH/Skolan för industriell teknik och management (ITM)

    Author : Oskar Hildestrand; Emma Karlberg; [2023]
    Keywords : Backbox; Tow bar cargo box; Product analysis; User-centered design; User experience; Product Design; Mechanical Design and Combination lock; Bakbox; Dragkroksbox; Produkt analys; Användarcentrerad design; Användarupplevelse; Produkt design; Mekanisk konstruktion; Kombinationslås;

    Abstract : Due to the climate crisis, electrical vehicles are on the upswing. To optimize the range of electric cars, aerodynamics is an important factor to consider. Therefore, cargo boxes mounted on the tow bar, often called backboxes, have become an interesting alternative to the standard roof mounted cargo box. READ MORE

  6. 5. CFD Analysis of the Flow Around a Paraglider Wing

    University essay from KTH/Teknisk mekanik

    Author : Caterina Gennari; [2023]
    Keywords : Paraglider Wing; CFD; RANS; DES; Aerodynamics; Aerodynamic Hysteresis; FSI; Deformable Structure; Membrane; Shell Elements;

    Abstract : In this study, the characteristics of the flow around a paraglider wing were investigated through the use of Computational Fluid Dynamics (CFD) simulations by solving both Reynolds Averaged Navier-Stokes equations and Delayed Detached Eddy Simulations were employed. This allowed the observation of how the unique shape of the canopy of a paraglider can influence the behaviour of the flow and how aerodynamic hysteresis can manifest on this sort of wing. READ MORE
