  1. 1. Investigation of Emission Characteristics for Diluted Flames and Renewable Fuels in Gas Turbine Combustors

    Författare :Fredrik Hermann; Kraftverksteknik; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; framdrivningssystem; Motorer; termodynamik; Motors and propulsion systems; Termisk teknik; applied thermodynamics; Thermal engineering; combustor rig experiments; combustor reactor models; synthetic fuel; liquid fuel; gaseous fuel; UHC; CO; NOx; emission measurements; CO2 enriched; humidified combustion; diluted combustion; premixed combustion; Gas turbine; combustion chamber; Energiforskning; Energy research;

    Sammanfattning : Gas turbines have served as economically profitable and reliable generators of power for the past few decades, and have mainly been used in simple and combined cycles. The increased restrictions on hazardous emissions and the increased demand for profitability have created new prospects for innovative power cycles. LÄS MER

  3. 2. Climate Policy for Aviation - Analyses of measures at multiple levels

    Författare :Anna Katarina Elofsson; Chalmers tekniska högskola; []
    Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; local governance; biofuels; climate policy instruments; aviation;

    Sammanfattning : The aviation sector is affected by local, national, multinational (EU) and/or global climate policies targeting domestic, intra-European and intercontinental flights in different and partly overlapping ways. The aim of this thesis is to strengthen further knowledge on climate policy for aviation at multiple governance levels and by doing so contribute to a more informed policy process. LÄS MER

  4. 3. Analysis of concepts to reduce the environmental impact of aviation

    Författare :Linda Larsson; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Turboprop; Contrails; Turbofan; Aviation; Open rotor; Aircraft engine; Environment;

    Sammanfattning : The average yearly increase in passenger kilometres travelled by air has been 5.8 % over the last 40 years. Fortunately the fuel consumption has not increased at the same rate. Over the same time period the average increase in fuel sold has been 2. LÄS MER

  5. 4. Aviation and the Environment- Evaluation of High Propulsive Efficiency Engines

    Författare :Linda Larsson; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Aircraft engine; Environment; Open rotor; Turbofan; Aviation;

    Sammanfattning : There has been more than a tenfold increase in passenger kilometers traveled over the last 40 years. The highest rate of growth today is in developing countries such as China and India. These countries also have the two largest populations in the world. LÄS MER

  7. 5. Conceptual Design of Propulsion Systems for Boundary Layer Ingestion

    Författare :Sebastian Samuelsson; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; turbo-electric aircraft; performance modeling; Aviation; boundary layer ingestion; aircraft engine; conceptual design; propulsion integration;

    Sammanfattning : To reduce the climate impact of aviation new aircraft and engine concepts as well as improved design methods are needed. In this thesis, two fronts are explored. The first concerns improved methods for the conceptual design of the engine. LÄS MER
