  1. 1. Small-scale wave energy converter for wave tank facility

    Uppsats för yrkesexamina på avancerad nivå, Uppsala universitet/Elektricitetslära

    Författare :Samir Asseh; [2023]
    Nyckelord :Wave power; small-scale; Wave tank; facility; Renewable resources; damping; froude scaling; magnets; copper coil; Uppsala University; buoy; MATLAB; COMSOL; PTO; WEC; Electricicity generation.; Förnybar energi; Vågtank; Vågkraft;

    Sammanfattning : A small-scale wave energy converter was designed and built for teaching and academic purposes to be used at The Division for Electricity, in the Ångström Laboratory at Uppsala University. The design of the power take-off (PTO) makes use of magnets passing through a copper coil for electricity generation. LÄS MER

  3. 2. RF Compressor (SLED) Phase-Modulation to Reduce Peak Fields in the MAX IV Linear Accelerator

    Master-uppsats, Lunds universitet/Institutionen för elektro- och informationsteknik

    Författare :Joel Ekström; [2023]
    Nyckelord :Accelerator; MAX IV; LINAC; Phase-modulation; SLED; Pulse compression; Technology and Engineering;

    Sammanfattning : Modern particle accelerators need strong electric fields in order to produce high energy particles. Such high voltages are typically reached by injecting pulsed radio frequency power through several steps of amplification. At the end, pulse compression is used to further improve the energy gain at the cost of pulse-length. LÄS MER

  4. 3. Mechanical design guidelines and criteria for mooring components in wave energy devices : Finding the optimum chain and shackle parameters

    Uppsats för yrkesexamina på avancerad nivå, Uppsala universitet/Tillämpad mekanik

    Nyckelord :Chain; shackle; finite element method; wave energy converter; WEC; Kedja; kätting; schackel; finita element metoden; vågkraftverk;

    Sammanfattning : Obtaining the perfect renewable energy source is one of the most important questions of our lifetime. One renewable energy source that could be of interest in this question because of the characteristics of the power that could be extracted from it is wave energy. LÄS MER

  5. 4. Gravity and surface tension-driven waves

    Master-uppsats, KTH/Teknisk mekanik

    Författare :Albin Hedblom; [2022]
    Nyckelord :Gravity surface waves; capillary-gravity surface waves; dispersion; experiment;

    Sammanfattning : In this thesis, gravity and surface tension-driven water waves are investigated by designing an experimental setup to track wave patterns using a 300 fps high speed camera. This is done to reproduce the theoretical diagram of the dispersion relation for surface waves in different teaching contexts. Surface waves are dispersive, i.e. LÄS MER

  7. 5. Model Design for Further Spray Deflector investigation

    Master-uppsats, KTH/Marina system

    Författare :Xinguo Wang; [2021]
    Nyckelord :High-Speed Craft; Model Design; Spray Deflector; Höghastighetshantverk; modelldesign; spraydeflektor;

    Sammanfattning : Planing hull is one solution to break the speed barrier of conventional hull, but as the boat reaches a high speed, massive whisker spray will be developed and attached to the hull, which causes a notable resistance increase. A Swedish company Peterstep invented an innovative spray deflector that can deflect the spray backwards and harvest kinetic energy from the spray. LÄS MER
