  1. 1. Large Eddy Simulation of Turbulent Swirling Flows and Turbulent Premixed Combustion

    University dissertation from Fluid Mechanics

    Author : Ping Wang; Lunds universitet.; Lund University.; [2005]
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; fluid dynamics; Gases; flamelet model; flame wrinkle; large eddy simulation; vortex breakdown; turbulent premixed combustion; level set G-equation; swirling flow; plasmas; Gaser; fluiddynamik; plasma; Energy research; Energiforskning;

    Abstract : With the increasing concerns about our environment and human health, more and more stringent emission limits have been specified. These adopted and still coming emission limits require and promote more accurate, less experiential methods to design and develop the combustors. READ MORE

  2. 2. Direct Numerical Simulation and Modelling Study of the Structures and Propagation of Partially Premixed Turbulent Flames

    University dissertation from Fluid Mechanics

    Author : Vivianne Holmen; Lunds universitet.; Lund University.; [2015]
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

    Abstract : Turbulent partially premixed flames are found in common combustion applications, such as the lifted jet flames in diesel engines. There is less theory surrounding the structure and propagation of turbulent partially premixed flames than for classical premixed flames and diffusion flames, especially in regards to modelling.

  3. 3. Large Eddy Simulation of Turbulent Reactive Flows under HCCI Engine Conditions

    University dissertation from Fluid Mechanics

    Author : Tobias Joelsson; Lunds universitet.; Lund University.; Lunds universitet.; Lund University.; [2011]
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

    Abstract : Popular Abstract in English In the past ten years, homogeneous charge compression ignition (HCCI) combustion has been one of the subjects receiving great research interests in the combustion research community and the engine industry. This is because HCCI combustion processes have the potential of not only capable providing high efficiency like diesel engine combustion, but also producing much lower emissions of NOx and soot than diesel engines.
