  5. 19. Rotational Coherent Anti-Stokes Raman Spectroscopy: Experimental and Theoretical Developments in Gas-phase Thermometry

    Författare :Mikael Afzelius; Förbränningsfysik; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; collision line-broadening calculations; combustion laser diagnostics; Laserteknik; Laser technology; CARS; coherent laser spectroscopy; Fysicumarkivet A:2004:Afzelius;

    Sammanfattning : Dual-broadband pure rotational coherent anti-Stokes Raman spectroscopy was investigated in terms of thermometry and species concentration measurement for studies of combustion. The modelling of rotational CARS spectra under conditions of high pressure at room temperature was investigated. LÄS MER

  7. 20. A Detailed Modeling Study for Primary Reference Fuels and Fuel Mixtures and Their Use in Engineering Applications

    Författare :Syed Ahmed; Förbränningsfysik; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Teknik; Detailed mechanism; Lumping procedure; Reduction technique.; Technological sciences; Fuel blends; n-heptane; Primary Reference Fuels PRF ; Toulene; iso-octane;

    Sammanfattning : The aim of this work is to generate detailed and simplified kinetic models for the oxidation of the Primary Reference Fuels (PRF) n-heptane, iso-octane and their mixtures, with low numbers of species and reactions. These mechanisms are consistent in terms of the choice of kinetic parameters for the different reaction classes. LÄS MER
