  3. 2. Materialmodellers applicerbarhet för multifasflöden med icke-Newtonska vätskor i Ansys CFX

    Kandidat-uppsats,

    Författare :Nils Wikström; David Hovstadius; [2022]
    Nyckelord :Ansys-CFX; Fluidmekanik; icke newtonska vätskor; multifasflöden; materialmodeller; solidtryck; navier-stokes ekvationer för multifasflöden;

    Sammanfattning : Material properties are very important to model correctly when calculating solutions for multiphase flows with non-Newtonian fluids. The models can make the solution converge or diverge depending on how it is chosen. This paper mainly focuses of the applicability of solid pressure and viscosity models in Ansys CFX. LÄS MER

  4. 3. Extensional Instability in Complex Fluids: A Computational Study

    Master-uppsats, KTH/Strömningsmekanik och Teknisk Akustik

    Författare :Muhammed Abdulrazaq; [2020]
    Nyckelord :Complex Fluids; Computational Rheology; Elastoviscoplastic Fluids; Instability.; Komplexa vätskor; Beräkningsreologi; Elastoviskoplastiska vätskor; Instabilitet.;

    Sammanfattning : In this study, instability and failure in complex fluids (Elastoviscoplastic fluids) is explored using the classic Considère (F˙ < 0) and stress curvature (σ¨ < 0) criteria. Employing the Saramito model, numerical simulation of the extensional protocol on non-Newtonian fluids is carried out. LÄS MER
