  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; finite difference methods; high-order accuracy; summation-by-parts; stability; energy estimates; finite volume methods; Numerical Analysis; Numerisk analys;

    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

  3. 3. 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 : NATURVETENSKAP; NATURAL SCIENCES; hybrid methods; finite difference methods; finite volume methods; coupling procedure; stability; efficiency; artificial dissipation; Beräkningsvetenskap med inriktning mot numerisk analys; Scientific Computing with specialization in Numerical Analysis;

    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
