  3. 3. Atmosphere-ocean Interactions in Swell Dominated Wave Fields

    University dissertation from Uppsala : Acta Universitatis Upsaliensis

    Author : Alvaro Semedo; Uppsala universitet.; [2010]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Waves; Wind sea; Swell; Swell propagation; MABL; Air-sea interaction; Momentum flux; Wave climate; Coupling; Wave age; Empirical Orthogonal functions; Wave model; Climate model; WAM; RCA; wave heights; NATURAL SCIENCES Earth sciences Atmosphere and hydrosphere sciences Meteorology; NATURVETENSKAP Geovetenskap Atmosfärs- och hydrosfärsvetenskap Meteorologi; Meteorologi; Meteorology;

    Abstract : Ocean wind waves represent the atmosphere-ocean boundary, playing a central role in the air-sea exchanging processes. Heat, mass and momentum are transferred across this boundary, with waves mediating the exchange of principally the momentum between the winds and the ocean surface. During the generation process waves are called wind sea. READ MORE

  4. 4. Wave Powered Desalination

    University dissertation from Uppsala : Uppsala universitet

    Author : Jennifer Leijon; Uppsala universitet.; [2018]
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; wave power; desalination; marine renewable energy sources; marine current; freshwater; Engineering Science; Teknisk fysik;

    Abstract : The aim of this licentiate thesis is to investigate opportunities to produce fresh-water and electricity using marine renewable energy sources, such as wave power and marine current power, for water scarce areas. It summarizes the ongoing work within the field and suggests some possibilities of future re-search. READ MORE

  5. 5. Wave Energy Conversion Linear Synchronous Permanent Magnet Generator

    University dissertation from Uppsala : Acta Universitatis Upsaliensis

    Author : Oskar Danielsson; Uppsala universitet.; [2006]
    Keywords : Engineering physics; Finite element method; linear synchronous generator; longitudinal end effect; permanent magnet; point absorber; offshore testing; wave power; Teknisk fysik;

    Abstract : This thesis studies the electric aspects of a linear synchronous permanent magnet generator. The generator is designed for use in a wave energy converter, which determines the fundamental requirements of the generator. The electromagnetic properties of the generator are investigated with a finite element based simulation tool. READ MORE
