  1. 1. Verification and validation of the implementation of an Algebraic Reynolds-Stress Model for stratified boundary layers

    University essay from KTH/Teknisk mekanik

    Author : Martina Formichetti; [2022]
    Keywords : Atmospheric boundary layer; turbulence modelling; stratified flows; eddy viscosity; eddy diffusivity;

    Abstract : This thesis studies the implementation of an Explicit Algebraic Reynolds-Stress Model(EARSM) for Atmospheric Boundary Layer (ABL) in an open source ComputationalFluid Dynamics (CFD) software, OpenFOAM, following the guidance provided by thewind company ENERCON that aims to make use of this novel model to improvesites’ wind-field predictions. After carefully implementing the model in OpenFOAM,the EARSM implementation is verified and validated by testing it with a stratifiedCouette flow case. READ MORE

  3. 2. Nanoparticle Removal and Brownian Diffusion by Virus Removal Filters: Theoretical and Experimental Study

    University essay from Uppsala universitet/Nanoteknologi och funktionella material

    Author : Olof Gustafsson; [2017]
    Keywords : virus removal filtration; Péclet number; nanocellulose; hydrodynamic constraint; convective capture; diffusion;

    Abstract : This study aims to examine the throughput of nanoparticles through a Cladophora cellulose based virus removal filter. The effect of Brownian motion and flow velocity on the retention of 5 nm gold nanoparticles, 12.8 nm dextran nanoparticles and 28 nm ΦX174 bacteriophages was examined through MATLAB simulations and filtration experiments.

  4. 3. Mass conservative network model for convective net flow in a complex urban geometry

    University essay from Umeå universitet/Institutionen för fysik

    Author : Linus Olofsson; [2016]
    Keywords : Network model; Street canyons; Intersections; Urban dispersion; CFD data; CFD simulations; Atmospheric exchange;

    Abstract : When simulating air flows in an urban environment, for e.g. pollutant dispersion investigations, today's main tool is advanced computational fluid dynamics simulations. These simulations take a lot of time and resources to perform, even for small geometries. READ MORE

  5. 4. Development of Brake Cooling

    University essay from Högskolan i Halmstad/Akademin för ekonomi, teknik och naturvetenskap

    Author : Arne Lindgren; [2016]
    Keywords : mechanical; engineering; CFD; CATIA; CAD; Koenigsegg; Halmstad; university; heat; transfer; cooling; flow; analysis; bachelor; thesis; brake; disc; racing; maskiningenjör; utveckling; konstruktion; bromskylning; CFD; CATIA; CAD; Koenigsegg; datorstödd; produktframtagning; högskolan; Halmstad; värmeöverföring; kylning; flödessimulering; examensarbete; exjobb; examensjobb; skivbroms; skiva; bromsar;

    Abstract : Sports cars need efficient brake cooling as they shall perform well during hard driving conditions, like for example race track driving. Most sports cars use ducts that capture ambient airflow and directs this flow over the brakes to improve the cooling. READ MORE
