  1. 1. 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.

    University essay from Uppsala universitet/Institutet för rymdfysik, Uppsalaavdelningen; Uppsala universitet/Institutionen för fysik och astronomi

    Author : Apostolos Kolokotronis; [2023]
    Keywords : ;

    Abstract : Saturn's rings have long been thought to provide the planetary atmosphere with infalling material, affecting both its chemical composition and physical properties (e.g. temperature). 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. FEM Analysis of paperboard packaging

    University essay from KTH/Hållfasthetslära

    Author : Wen-Che Li; [2022]
    Keywords : ;

    Abstract : The work aims to provide a finite element model using Ansys Workbench for realistically simulating paperboard packages. The geometrical properties of a package and the loading conditions were altered to investigate their influence on the box behavior and the applicability of Ansys as the finite element solver for paperboard material.

  6. 5. Evaluating the Implementation and Results of EU 2017/745

    University essay from KTH/Medicinteknik och hälsosystem

    Author : Olivia Gustafsson; [2022]
    Keywords : MDR; regulation; implementation evaluation; implementation result; MDR; förordning; implementeringsutvärdering; implementeringsresultat;

    Abstract : The new regulation on medical devices, EU 2017/745, came into force in May 2021 meaning that all economic operators in the industry need to adhere to new, stricter requirements. As there is yet no common practice on how to implement and comply with the new requirements, many struggles with this. READ MORE
