  1. 1. Permeability of non-crimp fabrics : a computational fluid dynamics approach

    University dissertation from Luleå : Luleå tekniska universitet

    Author : Markus Nordlund; [2004]
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Strömningslära; Fluid Mechanics;

    Abstract : In the present market for manufacturing of high performance structural parts for various applications such as aerospace, transportation, infrastructure, marine, sports and recreation, low weight, high performance composites are preferable. Non-Crimp Fabrics (NCFs) are often used for such applications due to its high mechanical properties and often cost effective production. READ MORE

  2. 2. Large Eddy Simulation of Complex Turbulent Flows

    University dissertation from Division of Fluid Mechanics, Department of Energy Sciences, Lund Institute of Technology, Lund University

    Author : Magnus Berglund; Lund University.; Lunds universitet.; [2006]
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Gases; fluid dynamics; plasmas; Computational Fluid Dynamics CFD ; Large Eddy Simulation; Complex Turbulent Flows; plasma; Gaser; fluiddynamik;

    Abstract : This thesis concerns the Large Eddy Simulation methodology and its application to predict complex turbulent flows at high Reynolds numbers, and at times also with high Mach numbers. The meaning of the word ?complex? refers both to the presence of complex flow phenomena and the, often, complex geometry of man-made devices restricting the flow. READ MORE

  3. 3. Numerical Modeling of Flows Related to Gas Turbine Combustors

    University dissertation from Department of Heat and Power Engineering, Lund university

    Author : Robert-Zoltán Szász; Lund University.; Lunds universitet.; [2004]
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; plasma; fluid dynamics; plasmas; Gaser; fluiddynamik; Gases; vortex breakdown; swirl; CFD; gas turbine;

    Abstract : The thesis focuses on the numerical simulation of the flow field in gas turbine burners. Due to tougher and tougher requirements on low levels of emission of pollutants there is a need for new combustion technologies. In gas turbines one method to attain low pollutant levels is the use of lean premixed combustion. READ MORE
