  1. 1. Analysis and Evaluation of Innovative Aero Engine Core Concepts

    Författare :Lei Xu; Chalmers tekniska högskola; []
    Nyckelord :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;

    Sammanfattning : 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.

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

    Författare :Egill Maron Thorbergsson; Chalmers tekniska högskola; []
    Nyckelord :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;

    Sammanfattning : 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. LÄS MER

  4. 3. Evaluation, Experience and Potential of Gas Turbine Based Cycles with Humidification

    Författare :Torbjörn Lindquist; Kraftverksteknik; []

    Sammanfattning : Gas turbines, in simple and combined cycle, are common and economically profitable on the power generating market today. Several new cycles have been proposed as future competing technologies, but all studies about these cycles have, so far, been paperwork. LÄS MER

  5. 4. Developing Humidified Gas Turbine Cycles

    Författare :Michael Bartlett; KTH; []
    Nyckelord :advanced gas turbine cycles; evaporative; humidified; power; heat and power;

    Sammanfattning : As a result of their unique heat recovery properties,Humidified Gas Turbine (HGT) cycles have the potential todeliver resource-effective energy to society. The EvaporativeGas Turbine (EvGT) Consortium in Sweden has been studying thesetypes of cycles for nearly a decade, but now stands at acrossroads, with commercial demonstration remaining. LÄS MER

  7. 5. Towards Environmentally Friendly Aero Engines

    Författare :Rickard Avellan; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; geared turbofan; energy efficiency; turbofan; environmentally friendly; DDTF; aero engines; GTF; aircraft;

    Sammanfattning : Since the introduction of subsonic jet driven commercial aircraft, incremental improvements in overall efficiency has been a driving requirement as well as a selling argument for the engine industry. The historical overall efficiency improvement is the result of continuous advances in aerodynamic design, increase of overall pressure ratios, turbine inlet temperatures and propulsive efficiencies in parallel with the development of stronger and lighter materials.
