  4. 4. Numerical Conformal Mappings for Regions Bounded by Smooth Curves

    Detta är en avhandling från Växjö : Matematiska och systemtekniska institutionen, Växjö universitet

    Författare :Anders Andersson; [2006]
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Schwarz–Christoffel mapping; rounded corners; tangent polygons; outer polygon; zipper algorithm; MATHEMATICS Applied mathematics; MATEMATIK Tillämpad matematik; MATHEMATICS Applied mathematics Numerical analysis; MATEMATIK Tillämpad matematik Numerisk analys;

    Sammanfattning : In many applications, conformal mappings are used to transform twodimensional regions into simpler ones. One such region for which conformal mappings are needed is a channel bounded by continuously differentiable curves. LÄS MER

  5. 5. A numerical study of two-fluid models for dispersed two-phase flow

    Detta är en avhandling från Stockholm : KTH

    Författare :Reynir Levi Gudmundsson; Björn Sjögreen; Anders Petersson; [2005]
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Numerical analysis; two-phase flow; two-fluid mode; well-posedness; numerical experiments; Numerisk analys; MATHEMATICS Applied mathematics Numerical analysis; MATEMATIK Tillämpad matematik Numerisk analys;

    Sammanfattning : In this thesis the two-fluid (Eulerian/Eulerian) formulation for dispersed two-phase flow is considered. Closure laws are needed for this type of models. We investigate both empirically based relations, which we refer to as a nongranular model, and relations obtained from kinetic theory of dense gases, which we refer to as a granular model. LÄS MER
