  1. 6. Laser Diagnostics Applied to Lean Premixed Swirling Flames - Simultaneous Flow Field and Scalar Measurements

    Författare :Per Petersson; Förbränningsfysik; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Volumetric Velocimetry; Low-swirl Flames; Premixed Flames; Turbulent Combustion; Particle Image Velocimetry; Laser Diagnostics; A.2014:Petersson; Combustion Diagnostics;

    Sammanfattning : The work reported here includes experimental studies of lean premixed swirling flames. Various laser-based optical diagnostic techniques were used to collect information under different operational conditions. Combined flow- and scalar field measurements were performed at high repetition rates for detailed studies of the turbulent flames. LÄS MER

  3. 7. Experimental studies of turbulent flames at gas turbine relevant burners and operating conditions

    Författare :Xin Liu; Förbränningsfysik; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Turbulent Combustion; Gas Turbine; Laser diagnostic; Fuel flexibility; Plasma-assisted combustion; Ammonia flame; High pressure;

    Sammanfattning : With the increasing demand of using alternative and renewable fuels, it becomes of vital importance to consider the fuel flexibility when designing a new burner for gas turbines. Hydrogen-enriched fuel and ammonia are two of these potential fuels, and they can significantly change the operability range of the gas turbines. LÄS MER

  4. 8. CFD Modelling of Hydrogen Rich Biomass Syngas Combustion

    Författare :Nikolaos Papafilippou; Rikard Gebart; Kentaro Umeki; Muhammad Aqib Chishty; Christophe Duwig; Luleå tekniska universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; CFD; RANS; LES; FGM; Turbulent Combustion; Numerical Combustion; Swirling Flows; Gas Turbines; Biomass Syngas; Hydrogen; Energiteknik; Energy Engineering;

    Sammanfattning : The loss of biodiversity, due to pollution and global warming, is more important and relevant now than it has ever been. Man made climate warming has its roots in the huge amount of CH4 and CO2 emissions, which have increased by 47% and 156% respectively since 1750. LÄS MER

  5. 9. Studies of Gas Turbines Combustion Chambers: Use of New Fuels and Development of New Tools

    Författare :Christophe Duwig; Strömningsteknik; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Termisk teknik; termodynamik; applied thermodynamics; Thermal engineering; Flamelets; LES; CFD; Gas Turbine; Combustion;

    Sammanfattning : The growing world electricity demand and environmental concerns pushes toward new technology for electricity production. Within the thermal processes for electricity production, two axis of research are being developed to meet the needs of the industry, namely using renewable fuels and new generation burners technology.

  7. 10. Mining for Meaning : using computational text analysis for social inquiry

    Författare :Miriam Hurtado Bodell; Marc Keuschnigg; Måns Magnusson; Peter Hedström; Laura Nelson; Linköpings universitet; []
    Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; Text-as-data; Analytical sociology; Meaning-making; Computational text analysis; Computational social science;

    Sammanfattning : People interpret their surroundings through associations, determining what they perceive as belonging or not belonging together. For instance, one individual may view immigrants as a beneficial addition to the domestic labor market, while another may perceive them as a threat to job opportunities for native citizens. LÄS MER
