  1. 1. Phosphor Thermometry: Advances in Technique Development and Applications

    Author : Fahed Abou Nada; Förbränningsfysik; []
    Keywords : Phosphor thermometry; Laser-based combustion diagnostics; Decay time phosphor thermometry; Fysicumarkivet A:2016:Abou Nada;

    Abstract : Understanding the mechanisms that govern the combustion processes is important for being able to further increase the efficiency ofcombustion devices. Temperature is considered to be one of the most important parameters controlling the progression and finalproducts of combustion. READ MORE

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

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

    Abstract : 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. READ MORE

  3. 3. 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; 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

    Keywords : NATURVETENSKAP; NATURAL SCIENCES; hydrogen combustion; laminar burning velocity; ICLAS; temperature dependence; heat flux method; Fysicumarkivet A:2015:Alekseev;

    Abstract : The laminar burning velocity and the flame structure are common targets for combustion studies aimed at detailed kinetic model development. In the present work, fuels relevant to hydrogen combustion were considered. READ MORE

  5. 5. Homogeneous Ignition - Chemical Kinetic Studies for IC-Engine Applications

    Author : Per Amnéus; Förbränningsfysik; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Skeletal mechanism; Mechanism reduction; n-heptane; iso-octane; formaldehyde; methane; Motors and propulsion systems; Motorer; framdrivningssystem; Physics; Fysik; Detailed chemistry; Kinetic calculations; Engine knock; Homogeneous charge compression ignition; HCCI; Fysicumarkivet A:2002:Amnéus;

    Abstract : Calculations on a Homogeneous Charge Compression Ignition (HCCI) engine have been performed. Zero-dimensional models were used. The simplest model compressed the gas to auto-ignition, using temperature and pressure at a certain crank angle position obtained from engine experiments. READ MORE
