  1. 1. Electric Energy Conversion Systems : Wave Energy and Hydropower

    Författare :Karin Thorburn; Mats Leijon; Petra Lundström; Uppsala universitet; []
    Nyckelord :Engineering physics; Ocean wave power; renewable energy; linear generator; farm simulation; Teknisk fysik;

    Sammanfattning : Electric energy conversion is an important issue in today's society as our daily lives largely depend on the supplies of energy. Two energy sources are studied for conversion in the present thesis, ocean waves and hydropower. The work focuses on the generator and the transmission of its output to the electric grid. LÄS MER

    Sammanfattning : Ice based Cool Thermal Energy Storage (CTES) systems have attracted much attention during last few decades. The reasons are mainly of economical and environmental nature. LÄS MER

  7. 5. Phase Change Phenomena During Fluid Flow in Microchannels

    Författare :Rashid Ali; Björn E Palm; Gian Piero Celata; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Microchannels; Boiling; Heat Transfer; Thermal energy engineering; Termisk energiteknik; SRA - Energy; SRA - Energi;

    Sammanfattning : Phase change phenomena of a fluid flowing in a micro channel may be exploited to make the heat exchangers more compact and energy efficient. Compact heat exchangers offer several advantages such as light weight, low cost, energy efficiency, capability of removing high heat fluxes and charge reduction are a few to mention. LÄS MER
