  2. 11. Development of an efficient solver for detailed kinetics in reactive flows

    Author : Andrea Matrisciano; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Tabulated chemistry; Progress Variable; Stochastic Reactor Model; Detailed chemistry;

    Abstract : The use of chemical kinetic mechanisms in CAE tools for reactive flow simulations is of high importance for studying and predicting pollutant formation. However, usage of complex reaction schemes is accompanied by high computational cost in both 1D and 3D-CFD frameworks. READ MORE

  5. 13. Numerical Modeling of Turbulent Combustion and Flame Spread

    Author : Zhenghua Yan; Institutioner vid LTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Technological sciences; Flame Spread; Pyrolysis; Heat Transfer; Radiation; CFD; Turbulent Combustion Modeling; Teknik;

    Abstract : Theoretical models have been developed to address several important aspects of numerical modeling of turbulent combustion and flame spread. The developed models include a pyrolysis model for charring and non-charring solid materials, a fast narrow band radiation property evaluation model (FASTNB) and a turbulence model for buoyant flow and flame.

  6. 14. Detailed Soot Modelling in Laminar and Turbulent Reacting Flows

    Author : Michael Balthasar; Förbränningsmotorer; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; soot; turbulent; flames; engines; turbines; carbon black; ionization; laminar; Physics; Fysik; Fysicumarkivet A:2000:Balthasar;

    Abstract : In the present work a detailed kinetic soot model is applied to study the formation and oxidation of soot particles in laminar premixed and turbulent non-premixed flames. The soot model used in this study is based on a detailed description of the chemical and physical processes involved in the formation of soot. READ MORE

  7. 15. Large Eddy Simulation of Turbulent Premixed and Partially Premixed Combustion

    Author : Eric Baudoin; Strömningsteknik; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

    Abstract : In this thesis, a computational fluid dynamics (CFD) approach is used to study turbulent premixed and partially premixed combustion. The CFD approach is based on large eddy simulation (LES) in which the large-scale structures of the flow are resolved on a grid, leaving only the small-scale structures (subgrid scales) to be modeled.
