  1. 1. Stability analysis of channel flow laden with small particles

    Author : Joy Klinkenberg; Luca Brandt; Cristian Marchioli; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Transition; modal analysis; non-modal analysis; Direct Numerical Simulations; multi-phase flow; heavy particles; light particles; particle-laden;

    Abstract : This thesis deals with the stability of particle laden flows. Both modal and non-modal linear analyses have been performed on two-way coupled particleladen flows, where particles are considered spherical, solid and either heavy or light. When heavy particles are considered, only Stokes drag is used as interaction term. READ MORE

  2. 2. Transition in Particle-laden Flows

    University dissertation from Stockholm : KTH Royal Institute of Technology

    Author : Joy Klinkenberg; Luca Brandt; Shuisheng He; [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

  3. 3. QCD Phenomenology of Heavy Particle Dynamics

    University dissertation from Department of Theoretical Physics, Lund University

    Author : Emanuel Norrbin; [2000]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; High energy interactions; heavy quarks; QCD; charm asymmetry; hadronization; string fragmentation; colour reconnection; leptoquarks; parton shower; cosmic rays; Kosmisk strålning; högenergi; Fysicumarkivet A:2000:Norrbin;

    Abstract : In this thesis the phenomenology of Quantum Chromo Dynamics (QCD) is studied in a variety of circumstances from both perturbative and non-perturbative perspectives. The main emphasis is on the production and hadronization of heavy particles, specifically heavy quarks, gauge bosons, leptoquarks and supersymmetric particles. READ MORE

  4. 4. Particles and unregulated emissions from heavy-duty engines

    University dissertation from Luleå : Luleå tekniska universitet

    Author : Kent Nord; [2002]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Chemistry of Interfaces; Gränsytors kemi;

    Abstract : Nowadays, the diesel engine is a widely used power source with complex emissions. In order to find out the impact from diesel exhaust on health and environment, both regulated and unregulated exhaust gas emission have to be evaluated. READ MORE

  5. 5. WHAT ARE THE CHARACTERISTICS OF AIRBORNE PARTICLES THAT WE ARE EXPOSED TO? Focus on Indoor Environments and Emissions from Biomass Fired District Heating

    University dissertation from Luleå : Luleå tekniska universitet

    Author : Aneta Wierzbicka; [2008]
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; particles; indoor environments; biomass combustion;

    Abstract : Ambient fine particulate matter PM2.5 (particles with a diameter smaller than 2.5 μm) has been associated with cardiovascular and respiratory morbidity and mortality. It has been shown that biomass burning for heat production purposes can generate large amounts of fine particles. READ MORE
