  1. 1. Rheology of dense particle suspensions in linear over-damped flow

    Master-uppsats, KTH/Strömningsmekanik och Teknisk Akustik

    Författare :Salar Zamani Salimi; [2021]
    Nyckelord :;

    Sammanfattning : Suspensions are composed of mixtures of particles and fluid and are omnipresent in natural phenomena and in industrial processes. While hydrodynamic interactions or lubrication forces between the particles are important in the dilute regime, they become of lesser significance when the concentration is increased, and direct particle contacts become dominant in the rheological response of concentrated suspensions, particularly those close to the maximum volume fraction where the suspension ceases to flow.

  3. 2. Dynamics of non-spherical particles in vortices : Accumulation of plastics in the ocean

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

    Författare :Carl Lijefors; Adrian Stenbäck; [2021]
    Nyckelord :;

    Sammanfattning : Today the plastic waste has made itself a permanent part of our marine environment, and have presented itself as a many faced problem. Becauseof this it is of grave importance to focus research on understanding thedynamics and accumulation of these plastic particles in various flows. LÄS MER

  4. 3. Transport of non-spherical particles in pipeflow with suction

    Master-uppsats, Luleå tekniska universitet/Institutionen för system- och rymdteknik

    Författare :Emil Wångby; [2020]
    Nyckelord :Brownian motion; Non-spherical particles; Pipe flow;

    Sammanfattning : The interest of how small non-spherical particles transport behaviour when transported in pipe-flow is of large interest in a variety applications. This kind of theory have been used when studying composite manufacturing and how particles behaves in the human lungs. LÄS MER

  5. 4. Mapping DFT to effective Hamiltonians

    Master-uppsats, Lunds universitet/Matematisk fysik; Lunds universitet/Fysiska institutionen

    Författare :Paul André; [2019]
    Nyckelord :DFT; Hamiltonians; Nuclear; Physics; Structure; Technology and Engineering;

    Sammanfattning : This thesis proposes a new effective Hamiltonian to represent the interactions taking place in the atomic nucleus. This estimated Hamiltonian is analogous to the Pairing-Plus-Quadrupole model and this work is focused exclusively on the quadrupole part, with the aim of describing nuclear structure in a computationally efficient way.

  7. 5. Normal and anomalous diffusion

    Master-uppsats, Fakulteten för teknik- och naturvetenskap

    Författare :Lars Fredriksson; [2010]
    Nyckelord :anomalous diffusion; latex; fluorescence; probes; anisotropic; isotropic;

    Sammanfattning : Diffusion can be classified as either normal or anomalous. A variety of experimental systems are evaluated to classify diffusion. Potential regressions and step size distributions are analysed. LÄS MER
