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

    Detta är en avhandling från Uppsala : Acta Universitatis Upsaliensis

    Författare :Magnus Svärd; Uppsala universitet.; Uppsala universitet.; [2004]
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; finite difference methods; high-order accuracy; summation-by-parts; stability; energy estimates; finite volume methods; Numerical Analysis; Numerisk analys;

    Sammanfattning : 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. LÄS MER
