  2. 16. Thermodynamic Modelling and Performance of Combined Solid Oxide Fuel Cell and Gas Turbine Systems

    Author : Jens Pålsson; Kraftverksteknik; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; vakuumteknik; vibrationer; akustik; Motors and propulsion systems; Motorer; framdrivningssystem; Gases; fluid dynamics; plasmas; plasma; hydraulik; Maskinteknik; vibration and acoustic engineering; hydraulics; vacuum technology; Modelling; Mechanical engineering; Solid oxide fuel cell; Hybrid system; Gaser; fluiddynamik;

    Abstract : Solid oxide fuel cells (SOFCs) are a ceramic type of fuel cell operating at elevated temperatures. By utilising the thermal energy from the SOFC in a heat engine, a hybrid cycle with high performance can be achieved. One promising concept is a pressurised SOFC in combination with a recuperated gas turbine cycle. READ MORE

  4. 17. Interface Defeat and Penetration: Two Modes of Interaction between Metallic Projectiles and Ceramic Targets

  6. 19. Study of the Apparent Kinetics of Biomass Gasification Using High-Temperature Steam

    Author : Aliaksandr Alevanau; Weihong Yang; Wlodzimierz Blasiak; Anna Ponzio; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; high temperature gasification; random pore model; grain model; volumetric model; TGA; Thermal energy engineering; Termisk energiteknik; SRA - Energy; SRA - Energi;

    Abstract : Among the latest achievements in gasification technology, one may list the development of a method to preheat gasification agents using switched ceramic honey combs. The best output from this technology is achieved with use of water steam as a gasification agent, which is heated up to 1600 °C. READ MORE

  7. 20. A Statistical Approach to Near Dry Machining

    Author : Marina Isaksson; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; cooling; turning; carbide; lubrication.; aerospace; Near-dry-machining; ceramic; MQL;

    Abstract : To substantiate the implementation of near dry machining in such a demanding industry as the aerospace industry, it is essential to have a broad understanding about the phenomena behind near dry machining. The conditions for the aerospace industry is stated in such a way, that changes or method development of the process had to be very well founded before it could be executed. READ MORE
