  1. 1. Combustion Simulations with reduced mechanisms using hybrid optimization

    Kandidat-uppsats, Lunds universitet/Fysiska institutionen; Lunds universitet/Förbränningsfysik

    Författare :Marius Burman Ingeberg; [2018]
    Nyckelord :Optimization; Reduced mechanism; Hybrid optimization; simulated annealing; Genetic algorithm; Physics and Astronomy;

    Sammanfattning : In order to simulate complex combustion systems, the kinetic mechanisms describing the chemical processes have to be reduced. To minimize the error introduced by the reduction, coefficients of the reaction rates included in the mechanisms can be adjusted in ways so that simulations using the reduced mechanism behave like simulations that use detailed mechanisms.

  2. 2. Temperature measurement in flames using TLAF, alkali emission and OH UV absorption

    Magister-uppsats, Lunds universitet/Fysiska institutionen; Lunds universitet/Förbränningsfysik

    Författare :Yuhe Zhang; [2018]
    Nyckelord :Physics and Astronomy;

    Sammanfattning : There is a continued need for reliable and convenient nonintrusive thermometric techniques for better understanding and effective control of combustion related processes. In this thesis, three spectroscopic thermometric methods were studied to evaluate the hot flue gas temperatures provided by a multi-jet burner. LÄS MER

    Sammanfattning : The transport sector is one of many markets facing new challenges in the pursuit of reduced greenhouse gas emissions. The people at Volvo Powertrain in Malmö are continuously working to develop new and improved techniques that are able to live up to the ever-increasing legislations. LÄS MER

  5. 5. Tunable diode laser absorptionspectroscopy of atomic potassium in a KOH-seeded flat flame

    Master-uppsats, Umeå universitet/Institutionen för fysik

    Författare :Mirjam Eriksson; [2018]
    Nyckelord :;

    Sammanfattning : Potassium (K) is the main ash-forming element released from biomass during thermochemical conversion. A better understanding of K chemistry and monitoring of K species is needed to optimize combustion systems. LÄS MER
