  1. 1. Laminar Burning Velocity and Development of a Chemical Kinetic Model for Small Oxygenated Fuels

    Author : Moah Christensen; Förbränningsfysik; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Oxygenated fuels; Kinetic mechanism; Validation; Sensitivity; Laminar burning velocity; Heat flux method; Fysicumarkivet A:2016:Christensen;

    Abstract : The thesis work was performed with the aim of increasing knowledge and understanding of the combustion of oxygenated fuels and intermediates. This was accomplished in two steps: experimental measurements of the laminar burning velocity to expand current databases and development of a reaction mechanism. READ MORE

  2. 2. Laminar burning velocity of hydrogen and flame structure of related fuels for detailed kinetic model validation

    Author : Vladimir Alekseev; Förbränningsfysik; []
    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

  3. 3. Combustion of selected alternative liquid fuels at oxy-fuel conditions: experiments and modelling

    Author : Jenny D. Nauclér; Förbränningsfysik; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Alcohols; Nitromethane; Chemistry; Laminar burning velocity; Ignition; Combustion; Fysicumarkivet A:2016:Nauclér;

    Abstract : Combustion of fuels is a major source of energy and at the same time a threat to the environment. Carbon dioxide (CO2) emissions are one of the obstacles on the route to cleaner energy. Combining Carbon Capture and Storage-technology (CCS) with use of biofuels lead to a negative net release of CO2 can be achieved. READ MORE

  4. 4. Turbulent burning, flame acceleration, explosion triggering

    Author : V'yacheslav Akkerman; Vitaly Bychkov; Geoffrey Searby; Umeå universitet; []
    Keywords : NATURAL SCIENCES; NATURVETENSKAP; Turbulent combustion; flame acceleration; detonation explosion triggering; direct numerical simulations; Physics; Fysik;

    Abstract : The present thesis considers several important problems of combustion theory, which are closely related to each other: turbulent burning, flame interaction with walls in different geometries, flame acceleration and detonation triggering. The theory of turbulent burning is developed within the renormalization approach. READ MORE

  5. 5. Experimental investigation of premixed ammonia combustion at high Karlovitz number conditions

    Author : Qingshuang Fan; Förbränningsfysik; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Turbulent premixed combustion; Ammonia flames; Laser diagnostics; Flame structure; High Karlovitz number; Turbulent burning velocity; Fysicumarkivet A:2021:Fan;

    Abstract : This thesis aims to acquire deep knowledge on turbulent premixed combustion at high Karlovitz (Ka) number conditions with the help of laser-based diagnostic measurements.Considering that ammonia (NH3), as a carbon-free energy carrier, is a promising candidate for replacing conventional fossil fuels in the future, all the investigations in this work were carried out on ammonia/air premixed flames.
