  1. 1. Aerodynamics simulations of Scania trucks using OpenFOAM

    University essay from KTH/Teknisk mekanik

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

    Abstract : 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. READ MORE

    Abstract : Accurately modeling aerodynamic forces and moments are crucial for understanding thebehavior of an aircraft when performing various maneuvers at different flight conditions.However, this task is challenging due to complex nonlinear dependencies on manydifferent parameters. READ MORE

  4. 3. Design Optimization of Savonius Wind Turbine using CFD Simulations

    University essay from Uppsala universitet/Institutionen för elektroteknik

    Author : Vatsalkumar Manavar; [2023]
    Keywords : Savonius wind turbine; Computational fluid dynamics; Vertical axis wind turbine; Overlap ratio; Distance between blades; Power coefficient;

    Abstract : This thesis is based on a simulation of the Savonius wind turbine. The Savoniusturbine is a simple vertical axis device, which has half cylindrical blades attached to the main shaft opposite to each other which creates the drag force from incoming wind and generates mechanical torque which drives the generator for electricity generation.

  5. 4. 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

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

    University essay from KTH/Skolan för teknikvetenskap (SCI)

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

    Abstract : 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. READ MORE
