  1. 1. Aerodynamics simulations of Scania trucks using OpenFOAM

    Master-uppsats, KTH/Teknisk mekanik

    Författare :Ziyi Liu; [2024]
    Nyckelord :Heavy-duty truck; Computational fluid dynamics; Air drag; OpenFOAM;

    Sammanfattning : In the field of heavy-duty vehicles, fuel efficiency and environmental protection are factors that need to be focused on, while the aerodynamic drag generated during vehicle travelling is one of the most influential aspects. This thesis delves into the aerodynamic simulation of Scania trucks using the open-source Computational Fluid Dynamics (CFD) tool, OpenFOAM v2206. LÄS MER

  3. 2. System Identification of a Fixed-Wing UAV Using a Prediction Error Method

    Master-uppsats, Linköpings universitet/Reglerteknik

    Författare :Trulsa Eriksson; [2023]
    Nyckelord :System identification; Fixed-wing UAV; Modelling; Parameter estimation;

    Sammanfattning : Unmanned aerial vehicles (UAVs) is a rapidly expanding area of research due to their versatile usage, such as inspection of places inaccessible to humans and surveillance missions. This creates a demand for a reliable model that can accurately describe the dynamics of the system in order to improve the performance of the vehicle.

  4. 3. Statistical Analysis on Aerodynamics of Passenger Vehicles

    Master-uppsats, Uppsala universitet/Sannolikhetsteori och kombinatorik

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

    Sammanfattning : 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. LÄS MER

  5. 4. Aerodynamic Concept Evaluation of Formula Student Side Structure

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

    Författare :Gabriel Ågren; [2023]
    Nyckelord :Formula Student; KTH Formula Student; race car aerodynamics; CFD; Multi-element wing;

    Sammanfattning : Formula Student is a global engineering competition where university students collaborate to design, construct, and race formula-style cars. Aerodynamics is one aspect in the vehicle design that can improve on-track performance by increasing cornering and straight-line speed. LÄS MER

  7. 5. Improvement of the 1D CFD method for Thermal management of a Battery Electric Vehicle

    Master-uppsats, Linköpings universitet/Mekanisk värmeteori och strömningslära

    Författare :SASHWAT CHHETRI; [2022]
    Nyckelord :CFD; Electromobility; BEV; Thermal Management; Simulation;

    Sammanfattning : Electrification of vehicles is necessary to combat greenhouse gas emissions, whichcauses global warming and climate change. There has been a demand in the use ofBattery Electric Vehicles due to this increased awareness of sustainability. However,they have been beset with issues such as range and conservation of energy.
