  2. 1. Detailed simulations of droplet evaporation

    Author : Giandomenico Lupo; Christophe Duwig; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; droplet; evaporation; phase change; multicomponent; immersed boundary; droppe; förångning; fasövergång; multikomponent; nedsånkt rand;

    Abstract : Droplet evaporation (and condensation) is one of the most common instancesof multiphase flow with phase change, encountered in nature as well as intechnical and industrial applications. Examples include falling rain drops, fogsand mists, aerosol applications like electronic cigarettes and inhalation drugdelivery, engineering applications like spray combustion, spray wet scrubbing orgas absorption, spray drying, flame spray pyrolysis.

  4. 2. Phase-field modeling of surface-energy driven processes

    Author : Klara Asp Grönhagen; John Ågren; Suzana Fries; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Phase-field method; surface energy; solute drag; solid-state sintering; multicomponent multiphase flow; wetting; liquid-phase sintering; spinodal decomposition; CALPHAD; Materials science; Teknisk materialvetenskap;

    Abstract : Surface energy plays a major role in many phenomena that are important in technological and industrial processes, for example in wetting, grain growth and sintering. In this thesis, such surface-energy driven processes are studied by means of the phase-field method. READ MORE

  5. 3. Diffuse-Interface Simulations of Capillary Phenomena

    Author : Walter Villanueva; Gustav Amberg; Steffen Hardt; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; capillary-driven flows; wetting; Cahn-Hilliard Navier-Stokes system; multicomponent and multiphase flows; parallel adaptive computing; Other engineering mechanics; Övrig teknisk mekanik;

    Abstract : Fluid flows mainly driven by capillary forces are presented in this thesis. By means of modeling and simulations, interesting dynamics in capillary-driven flows are revealed such as coalescences, breakups, precursor films, flow instabilities, rapid spreading, rigid body motions, and reactive wetting.

  6. 4. Modeling and analysis of heat and mass transfer processes during in-vessel melt progression stage of light water reactor (LWR) severe accidents

    Author : Robert R. Nourgaliev; KTH; []
    Keywords : ;

    Abstract : The last two decades of nuclear industry are marked byconsiderable attention tonuclear power plant accidents with core meltdown, knownalsoas severe accidents(SA). Two wellknown severeaccidents, TMI (USA, 1979) and Chernobyl (USSR, 1986), igniteda new wave of publit cancern about safety of existing nuclearpower plants. READ MORE
