  3. 2. Numerical stability studies of one-phase and immiscible two-phase jets and wakes

    Författare :Outi Tammisola; Daniel Söderberg; Fredrik Lundell; Rama Govindarajan; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Fluid mechanics; Strömningsmekanik;

    Sammanfattning : The initial linear instability growth of two-dimensional plane wakes and jetsis investigated, by temporal two-dimensional global modes, and local spatialstability analysis. Comparisons are also made to experiments, direct numericalsimulations, and methods designed for weakly-non-parallel flows. LÄS MER

  4. 3. Numerical simulation of non-Newtonian fluids flow over surfaces

    Författare :Kazem Bazesefidpar; Outi Tammisola; Luca Brandt; Shahriar Afkhami; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; dynamic wetting; viscoelasticity; non-Newtonian fluids; contact- angle hysteresis; droplet spreading; self-propelled jumping; dynamisk vätning; viskoelasticitet; icke-Newtonska vätskor; kontaktlinjehysteres; dropparnas spridning på ytor; spontan hoppning av droppar från ytor; Teknisk mekanik; Engineering Mechanics;

    Sammanfattning : Wetting of surfaces by droplets of non-Newtonian fluids is important for various industrial and natural processes such as coating and cleaning of surfaces and inkjet printing, to name a few. Viscoelastic fluids are compounds of a very small amount of polymers and solvent. LÄS MER

  5. 4. Phase-changing flows: numerical methods and fully resolved simulations

    Författare :Nicolo Scapin; Luca Brandt; Christophe Duwig; Outi Tammisola; Matthias Ihme; KTH; []
    Nyckelord :Phase change; interface-resolved simulations; compressibility; evaporating droplets; evaporation-driven thermal convection.; Teknisk mekanik; Engineering Mechanics;

    Sammanfattning : Flows with evaporation and boiling are abundant in different contexts, such as geophysics, the biomedical sectors, and industrial applications. Spray combustion, boiling bubble flows, oceanic sprays, formation and evolution of clouds, spreading of infectious diseases are all relevant examples where a deeper understanding of phase-changing flows is of great importance.
