  1. 1. Lattice Boltzmann simulations of tracer diffusion in microswimmer suspensions

    Författare :Henrik Nordanger; Fysikalisk kemi; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Lattice Boltzmann; microswimmers; active matter; enhanced diffusion;

    Sammanfattning : Suspensions of microswimmers are a class of systems inherently out of equilibrium, due to the mechanical work continuously performed by a large number of active agents. Biological examples are plentiful, as many aquatic microorganisms have the ability to propel themselves. LÄS MER

  3. 2. On Microstructural Analysis of Porous Media Existing in Fuel Cells Using the Lattice Boltzmann Method
