    Abstract : Manufacturing of aero engine components requires attention to residual stress and final shape of the product in order to meet high quality product standards.This sets very high demands on involved manufacturing steps to meet design requirements. READ MORE

  3. 3. 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

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

    University dissertation from Linköping : Linköping University Electronic Press

    Author : Tobias Joelsson; Lunds universitet.; Lund University.; Lunds universitet.; Lund University.; [2011]

    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.
