  1. 1. Geomechanical testing of non-hardening grout : for determination of flowability and strength properties

    Uppsats för yrkesexamina på avancerad nivå, Luleå tekniska universitet/Geoteknologi

    Författare :Axel Barrdahl; [2022]
    Nyckelord :Non-hardening; Grout; Embankment dam; Repair; Fall cone; Uniaxial Compressive Strength; UCS; Triaxial;

    Sammanfattning : Due to an increasing amount of aging tendencies in Swedish embankment dams, failures such as internal erosion has become a more common problem. Internal erosion is a phenomenon where certain soil material within the embankment dam is removed, often over a longer period of time. LÄS MER

  3. 2. Predicting fillability of viscoelastic product in Tetra Recart

    Master-uppsats, Lunds universitet/Förpackningslogistik

    Författare :Nawapan Boonchum; Roxanne Mae V. Targa; [2020]
    Nyckelord :Meat batter; Filling machine; Rheology; Pressure drop; Non-Newtonian fluid; Agriculture and Food Sciences; Technology and Engineering;

    Sammanfattning : It is of interest to design a methodology in predicting the fillability of non-Newtonian viscoelastic product such as meat batter by analyzing its rheological properties, reducing the need to perform pilot plant scale tests. Meat batter with different added water produced in laboratory and pilot plant were analyzed to represent meat batters with different rheological characteristics and filling behaviour. LÄS MER

  4. 3. Numerical Solvers of the p-Stokes Equations with Applications in Ice-Sheet Dynamics

    Kandidat-uppsats, KTH/Skolan för teknikvetenskap (SCI)

    Författare :Sebastian Myrbäck; Jonatan Risberg; [2020]
    Nyckelord :;

    Sammanfattning : In glacier dynamics – i.e. the field of research concerning the movement of ice – intricate mathematical models are used to describe its motion. Ice can be considered as a highly viscous, non-Newtonian fluid, obeying a set of equations closely related to the well-known Navier-Stokes equations describing classical fluid mechanics. LÄS MER

  5. 4. 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

  7. 5. A Simulation of Landslide-Generated Waves Using a Fully Implicit ISPH

    Master-uppsats, Lunds universitet/Avdelningen för Teknisk vattenresurslära

    Författare :Kosei Nishida; [2020]
    Nyckelord :SPH; Landslide-generated waves; non-newtonian fluid; multiphase flow; Technology and Engineering;

    Sammanfattning : Smoothed Particle Hydrodynamics (SPH) is used to study the mechanisms of landslide-generated waves. As the landslide dynamics and the evaluation of impact forces acting on water are most important, landslide is modelled as a highly viscous fluid. Incompressible SPH (ISPH) is used for fluid simulation. LÄS MER
