  1. 1. Laminar and turbulent particle laden flows a numerical and experimental study

    University dissertation from Stockholm : KTH Royal Institute of Technology

    Author : Seyed Hamid Tabaeikazerooni; KTH.; [2019]
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Suspension flow; inertial effect; turbulent duct flow; finite-size particles; Immersed Boundary Method IBM ; Astigmatism Particle Tracking Velocimetry APTV ; Teknisk mekanik; Engineering Mechanics;

    Abstract : Particle laden flows are widespread in nature and in industrial applications. Dust storms, geophysical flows, pharmaceutical processes, fluidized beds and blood flow are only a few examples. Both global and local properties of a particle laden flow may alter significantly in comparison to the corresponding single phase flow. READ MORE

  2. 2. Numerical Study of Dispersed Two-phase Flows

    University dissertation from Fluid Mechanics

    Author : Zhilei Wu; Lund University.; Lunds universitet.; [2000]
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Thermal engineering; Teknik; Technological sciences; Eulerian Lagrangian model.; Eulerian Eulerian model; Lagrangian Particle Tracking; Large Eddy Simulation; Two-phase flow; Particle Image Velocimetry; applied thermodynamics; Termisk teknik; termodynamik;

    Abstract : This thesis considers the numerical study of dispersed two-phase flows.Numerical simulations have been done to investigate the particle trasportation/dispersion effect in turbulent two-phase flows. Both turbulent bubble/water flows and turbulent particle/air flows are studied. READ MORE

  3. 3. Experimental study of bubble dynamics and transport

    University dissertation from Division of Fluid Mechanics, Department of Energy Sciences, Lund Institute of Technology, Lund University

    Author : Gunilla Andrée; Lund University.; Lunds universitet.; [2006]
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Energiforskning; Energy research; Particle Streak Photography; Shadowgraph; Particle Image Velocimetry; Bubble dynamics; bubble transport;

    Abstract : The thesis concerns experimental studies of bubble motion and the transport of large particles and bubbles. Bubbly flows are encountered in many engineering applications where the bubbles play an important role for the mass transfer between the phases, e.g. in stirred reactors. READ MORE

  4. 4. Optical Diagnostics of Non-thermal Plasmas and Plasma-assisted Combustion

    University dissertation from Lund Report on Combustion Physics

    Author : Jiajian Zhu; Lund University.; Lunds universitet.; [2015]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; High-speed photography; Laser diagnostics; Planar laser-induced fluorescence; Plasma-assisted combustion; Non-thermal plasmas; Gliding arc discharge; Optical diagnostics; Particle tracking velocimetry; Fysicumarkivet A:2015:Zhu;

    Abstract : Non-thermal plasma is regarded as a collection of free electrons, ions and neutral particles that are not at local thermodynamic equilibrium. The high-energetic electrons formed in non-thermal plasmas are capable of generating chemically active species and modifying chemical kinetics in practical applications. READ MORE

  5. 5. Always on the wing - Fluid dynamics, flight performance and flight behavior of common swifts

    University dissertation from Department of Biology, Lund University

    Author : Per Henningsson; Lund University.; Lunds universitet.; [2010]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Apus apus; aerodynamics; animal flight; kinematics; vortex wake; digital particle image velocimetry; DPIV; common swift; tracking radar; wind tunnel; migration; roosting flight;

    Abstract : The aerodynamics and kinematics behind the flight of animals are relatively unknown. Although animal flight has been studied for several hundreds of years, it is only in recent time that we have the technical abilities to study the mechanistic basis of animal flight. READ MORE
