  2. 16. Solar receiver development for gas-turbine based solar dish systems

    Author : Lukas Aichmayer; Björn Laumert; Konstantinos Kyprianidis; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Concentrating solar power; volumetric solar receiver; development; experimental evaluation; validation; Koncentrerad solkraft; volumetrisk solmottagare; utveckling; experimentell utvärdering; validering; Energy Technology; Energiteknik;

    Abstract : Small-scale concentrating solar power plants such as micro gas-turbine based solar dish systems have the potential to harness solar energy in an effective way and supply electricity to customers in remote areas. In such systems, the solar receiver transfers the power of concentrated solar radiation to the working fluid of the power conversion cycle. READ MORE

  4. 17. On Electrical Machine Topologies for Electric Vehicle Applications

    Author : Konstantina Bitsi; Stefan Östlund; Sjoerd Bosga; Anouar Belahcen; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

    Abstract : The deployment of electric vehicles is considered a viable solution towardsreducing the global greenhouse-gas emissions and fossil-fuel consumption. Inorder to produce highly efficient and economically feasible electrical drivesystems, the selection of suitable electric motor designs is a key step. READ MORE

  5. 18. The Performance of a Multi Cylinder HCCI Engine using Variable Compression Ratio and Fast Thermal Management
