  1. 1. Particle Measurements Using Fluctuations in the Regular Transmittance of Light Through a Particle Dispersion Concentration and Particles size - Theory, Measurement Principles and Applications for Pulp and Paper Production

    University dissertation from Stockholm : KTH

    Author : Staffan Rydefalk; KTH.; [2009]
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Particle concentration; Particle size; Cylindrical particles; Large particles; Cellulose fibres; Wood pulp fibres; Suspensions; Particle length; Particle length distribution; Particle width; TECHNOLOGY Industrial engineering and economy Manufacturing engineering and work sciences Manufacturing engineering; TEKNIKVETENSKAP Industriell teknik och ekonomi Produktion och arbetsvetenskap Produktionsteknik;

    Abstract : The regular transmittance of light or similar radiation through a flowing suspension of particles fluctuates because of the random occurrence of particles in the beam.In the work presented here, a theory for this fluctuating behaviour with the emphasison dispersions of mm-length slender cylindrical particles having circular crosssections is given.

  2. 2. Luminosity evaluation and fragmentation studies for the DELPHI experiment at LEP

    University dissertation from Department of Physics, Lund University

    Author : Christina Zacharatou Jarlskog; Lund University.; Lunds universitet.; [2001]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; luminosity; hadronization; Z boson; strong coupling constant; Elementary particle physics; Elementarpartikelfysik; quantum field theory; Fysicumarkivet A:2001:Jarlskog; LEP; DELPHI; kvantfältteori; Physics; Fysik;

    Abstract : The first subject addressed in this thesis is the contribution of the VSAT luminosity to the lineshape analysis, i.e. to the extraction of the mass and width of the Z0 boson from LEP1 DELPHI data. The VSAT detector has contributed to the lineshape parameter determination by providing a relative luminosity measurement of high accuracy. READ MORE

  3. 3. Transition in Particle-laden Flows

    University dissertation from Stockholm : KTH Royal Institute of Technology

    Author : Joy Klinkenberg; KTH.; [2013]
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Transition; modal analysis; non-modal analysis; multi-phase flow; particle-laden; heavy particles; light particles;

    Abstract : This thesis presents the study of laminar to turbulent transition of particle laden flows. When a flow becomes turbulent, the drag increases one order of magnitude compared to a laminar flow, therefore, much research is devoted to understand and influence the transition. READ MORE

  4. 4. Particle-laden Turbulent Wall-bounded Flows in Moderately Complex Geometries

    University dissertation from Stockholm : KTH Royal Institute of Technology

    Author : Azad Noorani; KTH.; [2015]
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; turbulent; complex geometry; particle; Teknisk mekanik; Engineering Mechanics;

    Abstract : Wall-bounded turbulent dispersed multiphase flows occur in a variety of industrial, biological and environmental applications. The complex nature of the carrier and the particulate phase is elevated to a higher level when introducing geometrical complexities such as curved walls. READ MORE

  5. 5. Snow particle size investigations using digital image analysis - implications for ground observations and remote sensing of snow

    University dissertation from Stockholm : Department of Physical Geography and Quaternary Geology (INK), Stockholm University

    Author : Susanne Ingvander; Stockholms universitet.; [2011]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; snow; remote sensing; particle size; Antarctica; in-situ sampling; seasonal snow; Physical Geography; naturgeografi;

    Abstract : During the past century climate warming has caused rapid changes in the Cryosphere. This has increased the need to accurately monitor rates of change in snow and ice in remote or sparsely populated areas where environmental observing capacity is limited. Monitoring snow cover requires understanding of the snow pack and the snow surface attributes. READ MORE
