  6. 4. Advanced Laser-based Multi-scalar Imaging for Flame Structure Visualization towards a Deepened Understanding of Premixed Turbulent Combustion

    Author : Bo Zhou; Förbränningsfysik; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Laser Diagnostics; PLIF; High Spatial Resolution; Multi-scalar Instantaneous Visualization; HCO CH Radicals; Distributed Reaction Zone; Mild Combustion.; Combustion Regimes; Turbulence Flame Interaction; Turbulent Premixed Combustion; Fysicumarkivet A:2015:Zhou;

    Abstract : The work presented in the thesis concerns the developments of laser-based diagnostics and its application to the study of turbulent premixed combustion. The diagnostic developments, mainly concerned with planar laser-induced fluorescence (PLIF), are intended to provide instantaneous visualization of the key species originating from the combustion processes involved in the burning of hydrocarbons and nitrogen-containing fuels under turbulent conditions.

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

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

    Abstract : 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. READ MORE
