    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; [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

  4. 4. Optimization of sheet metal forming processes

    University dissertation from Linköping : Linköping University Electronic Press

    Author : Tomas Jansson; Karl Brian Nielsen; [2005]

    Abstract : The potential of using simulation and optimization techniques in the design of sheet metal forming processes has been investigated. Optimization has been used in a variety of sheet metal forming applications. 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; [2011]

    Abstract : Large Eddy Simulation (LES) modeling is developed to study homogeneous charge compression ignition (HCCI) combustion under different engine operation and mixture conditions, including real engine configurations and generic test cases. A previously developed HCCI model has been validated by comparing the simulation results with engine experiments. READ MORE
