  2. 16. Conceptual Gas Turbine Modelling for Oxy-fuel Power Cycles

    Author : Egill Maron Thorbergsson; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Semi-closed Oxy-fuel Combustion Combined Cycle; Graz cycle; Carbon capture and storage; oxy-fuel combustion combined cycles; conceptual compressor design;

    Abstract : The electricity consumption in the world is growing at an ever increasing rate. Today's electricity generation is highly dependent on combustion of fossil fuel. This leads to emissions of carbon dioxide into the atmosphere. Increased atmospheric CO2 concentration results in higher average surface temperature and climate change. READ MORE

    Abstract : Maximum asset performance is one of the major goals for electric power distribution system operators (DSOs). To reach this goal minimal life cycle cost and maintenance optimization become crucial while meeting demands from customers and regulators. READ MORE

  6. 19. Analysis and Evaluation of Innovative Aero Engine Core Concepts

    Author : Lei Xu; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; intercooled recuperated cycle; intercooler; intercooled cycle; multidisciplinary optimization; turbofan; innovative core; variable core cycle; thermal efficiency; aero engine;

    Abstract : Turbofan engines, which power the majority of the modern aircraft today, have achieved such a high maturity that small improvements of the engine performance requires a large investment. More innovative technologies, including those related to the engine cores, become increasinglyattractive due to the high fuel price in recent years as well as the strict regulations on emissions.
