  2. 1. Phase-changing flows: numerical methods and fully resolved simulations

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

    Abstract : 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.

  4. 2. The Internal Flow in Freezing Water Droplets

    Author : Linn Karlsson; Staffan Lundström; Anna-Lena Ljung; Jasmina Casals-Terré; Luleå tekniska universitet; []
    Keywords : ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Strömningslära; Fluid Mechanics;

    Abstract : The aim of this work has been to study the internal flow in freezing water droplets on a cold surface and to investigate the different heat transfer mechanisms involved. This is an interesting topic with a great number of applications, specifically in areas where the prevention of unwanted icing is important, e.g. READ MORE

  5. 3. Experimental studies of ice particle formation with tropospheric relevance

    Author : Erik Svensson; Göteborgs universitet; Göteborgs universitet; Gothenburg University; []
    Keywords : heterogeneous nucleation; water; freezing; cloud droplets; levitation; electrodynamic balance; light scattering; oxalic acid; kaolinite; dinitrogen pentoxide;

    Abstract : In their fourth assessment report, the Intergovernmental Panel on Climate Change points out the influence of particles suspended in air, known as an aerosol, as the main uncertainty in the understanding of the climate system. Aerosols affect climate in a number of ways. READ MORE

  6. 4. Advances in droplet evaporation

    Author : Giandomenico Lupo; Christophe Duwig; Sébastien Tanguy; KTH; []
    Keywords : ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Engineering Mechanics; Teknisk mekanik;

    Abstract : Droplet evaporation (and condensation) is one of the most common instances of multiphase flow with phase change, encountered in nature as well as in technical applications. Examples include falling rain drops, fogs and mists, aerosol applications like electronic cigarettes and inhalation drug delivery, and engineering applications like spray combustion, spray wet scrubbing or gas absorption, spray drying, flame spray pyrolysis.

  7. 5. Molecular structure and dynamics of liquid water : Simulations complementing experiments

    Author : Daniel Schlesinger; Lars G. M. Pettersson; Paola Gallo; Stockholms universitet; []
    Keywords : NATURAL SCIENCES; NATURVETENSKAP; NATURVETENSKAP; NATURAL SCIENCES; liquid water; supercooled water; molecular simulation; evaporative cooling; teoretisk fysik; Theoretical Physics;

    Abstract : Water is abundant on earth and in the atmosphere and the most crucial liquid for life as we know it. It has been subject to rather intense research since more than a century and still holds secrets about its molecular structure and dynamics, particularly in the supercooled state, i. e. the metastable liquid below its melting point.
