  1. 1. Stable High-Order Finite Difference Methods for Aerodynamics

    University dissertation from Uppsala : Acta Universitatis Upsaliensis

    Author : Magnus Svärd; Uppsala universitet.; Uppsala universitet.; [2004]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Numerical Analysis; Numerisk analys; finite difference methods; high-order accuracy; summation-by-parts; stability; energy estimates; finite volume methods; MATHEMATICS Applied mathematics Numerical analysis; MATEMATIK Tillämpad matematik Numerisk analys; Scientific Computing; Beräkningsvetenskap;

    Abstract : In this thesis, the numerical solution of time-dependent partial differential equations (PDE) is studied. In particular high-order finite difference methods on Summation-by-parts (SBP) form are analysed and applied to model problems as well as the PDEs governing aerodynamics. READ MORE

  2. 2. Hybrid Methods for Unsteady Fluid Flow Problems in Complex Geometries

    University dissertation from Uppsala : Acta Universitatis Upsaliensis

    Author : Jing Gong; Uppsala universitet.; Uppsala universitet.; [2007]
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; Beräkningsvetenskap med inriktning mot numerisk analys; Scientific Computing with specialization in Numerical Analysis; hybrid methods; finite difference methods; finite volume methods; coupling procedure; stability; efficiency; artificial dissipation; MATHEMATICS Applied mathematics Numerical analysis; MATEMATIK Tillämpad matematik Numerisk analys; Scientific Computing; Beräkningsvetenskap;

    Abstract : In this thesis, stable and efficient hybrid methods which combine high order finite difference methods and unstructured finite volume methods for time-dependent initial boundary value problems have been developed. The hybrid methods make it possible to combine the efficiency of the finite difference method and the flexibility of the finite volume method. READ MORE

  3. 3. Uncertainty Quantification and Numerical Methods for Conservation Laws

  4. 4. Finite Volume Methods on Quadrilateral and Moving Meshes

    University dissertation from Numerical Analysis, Lund University

    Author : Fredrik Svensson; Lund University.; Lunds universitet.; [2006]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; numerisk analys; system; kontroll; systems; control; numerical analysis; finite volume method; Datalogi; Computer science; moving mesh method; higher order reconstruction; hyperbolic conservation law;

    Abstract : The topic of this thesis is the study of finite volume methods for hyperbolic conservation laws on non-uniform meshes. A high-order hyperbolic reconstruction method is presented. The method is constructed for quadrilateral meshes, since more realistic hyperbolic problems involve more complicated problem domains than the standard rectangular ones. READ MORE
