  1. 1. Detailed simulations of droplet evaporation

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

    Sammanfattning : 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. 3. Experimental Studies of the Interaction of Atmospheric Aerosol Particles with Clouds and Fogs

    Författare :Göran Frank; Kärnfysik; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; unipolar charger; Physics; DMA; differential mobility analyser; DAA; droplet aerosol analyser; fog microstructure; cloud microstructure; fog droplet; cloud droplet; cloud; fysisk instrumentering; fog; Metrologi; physical instrumentation; Metrology; Kärnfysik; Nuclear physics; Fysik; Fysicumarkivet A:2001:Frank;

    Sammanfattning : In this work, cloud and fog droplet formation was studied in three joint field experiments. The instrument, the droplet aerosol analyser (DAA), has also been further developed and verified as part of this work. The DAA is an instrument especially developed for studies of cloud and fog droplet formation and growth. LÄS MER

  5. 4. Mixing and Evaporation at the Cloud Edge and Angular Dynamics of Small Crystals in Viscous Flow

    Författare :Johan Fries; Göteborgs universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; cloud microphysics; droplet evaporation; reactive flows; Jeffery orbits; shear flow;

    Sammanfattning : How liquid water in atmospheric clouds distributes over droplets of different sizes is important for the initiation of rainfall, and for the optical properties of the atmosphere. Droplet-number densities and droplet-size distributions change rapidly at turbulent cloud edges, where mixing of cloudy and dry air causes cloud dilution and droplet evaporation. LÄS MER

  7. 5. Optical Levitation of Charged Droplets

    Författare :Oscar Isaksson; Chalmers tekniska högskola; []
    Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; water; Optical manipulation; neutralization; Radiation Pressure; demonstration; Millikan Oil Drop experiment; evaporation;

    Sammanfattning : The development of an experimental system used to investigate charged droplets is presented. The experimental setup combines optical levitation with Millikan's classical oil drop experiment and has also been used as a mean to demonstrate fundamental physical phenomena. LÄS MER
