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

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

    Abstract : 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. READ MORE

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

    Author : Mayken Espinoza Andaluz; Värmeöverföring; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Porous media; lattice Boltzmann method; microscale; Gas-phase tortuosity; Porosity; Fuel Cell;

    Abstract : This Licentiate thesis aims to gain understanding related to the fluid behavior in porous media existent in fuel cells (FCs) at microscale. In order to achieve this; the widely used methodology for solving problems in porous media has been applied, the Lattice Boltzmann Method (LBM). READ MORE

  5. 3. On Diffusion Transport Properties in Fuel Cell Gas Diffusion Layers Using the Lattice Boltzmann Method

    Author : Mayken Espinoza Andaluz; Värmeöverföring; []
    Keywords : PEFC; lattice Boltzmann method; gas diffusion layers; porosity; Gas-phase tortuosity; permeability; inertial coefficient; diffusibility; pore-scale modeling;

    Abstract : The polymer electrolyte fuel cell (PEFC) is considered as one of the most promising devices for providing efficient, clean and noiseless conversion of chemical energy to electrical energy. This device can provide electrical and thermal energy for transport, mobile and stationary applications ranging in a wide range of power requirements. READ MORE
