  1. 1. Mass Conserving Simulations of Two Phase Flow

    Författare :Elin Olsson; Gunilla Kreiss; Stig Larsson; KTH; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; free boundary; two phase flow; level set method; conservative; Numerical analysis; Numerisk analys;

    Sammanfattning : Consider a mixture of two immiscible, incompressible fluids e.g. oil and water. Since the fluids do not mix, an interface between the two fluids will form and move in time. LÄS MER

  3. 2. Adaptive Finite Element Methods for Compressible Two-Phase Flow

    Författare :Erik Burman; Göteborgs universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; adaptive finite element methods; two-phase flow; compressible flow; conservation laws; hyperbolic systems; a posteriori error estimates; streamline diffusion; stability analysis; quantitative error control; adaptive algorithms; quantitative error control;

    Sammanfattning : In this thesis we develop, apply and analyse adaptive finite element methods with error control for compressible flow problems, focusing in particular on two-phase flow. The adaptive algorithms, aiming at quantitative error control with efficient use of computational resources, are based on a posteriori error estimates, where the error is estimated in terms of the computed solution, the local mesh-size and certain stability factors.

    Sammanfattning : This thesis considers the numerical study of dispersed two-phase flows.Numerical simulations have been done to investigate the particle trasportation/dispersion effect in turbulent two-phase flows. Both turbulent bubble/water flows and turbulent particle/air flows are studied. LÄS MER
