  1. 1. Inertial collisions in random flows

    Författare :Kristian Gustafsson; Göteborgs universitet.; Gothenburg University.; [2011]
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Collisions; nonlinear dynamical systems; particles and aerosols; random processes; suspensions; turbulent diffusion; turbulent flows;

    Sammanfattning : In nature, suspensions of small particles in fluids are common. An important example are rain droplets suspended in turbulent clouds. Such clouds can start to rain very quickly and the reason for this is still not fully explained, but it is believed that the turbulent motion in the cloud plays an important role. LÄS MER

  5. 5. Molecular Hole Punching Impulse Driven Reactions in Molecules and Molecular Clusters

    Detta är en avhandling från Stockholm : Department of Physics, Stockholm University

    Författare :Michael Gatchell; Stockholms universitet.; [2016]
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; PAHs; Fullernes; Reactions; Clusters; Interstellar Medium; Fragmentation; Non-Statistical Fragmentation; Collisions; Experiments; Molecular Dynamics; Density Functional Theory; Physics; fysik;

    Sammanfattning : When molecules are excited by photons or energetic particles, they will cool through the emission of photons, electrons, or by fragmenting. Such processes are often thermal as they occur after the excitation energy has been redistributed across all degrees-of-freedom in the system. LÄS MER
