  1. 1. Laser Sheet Imaging and Image Analysis for Combustion Research

    Author : Rafeef Abu-Gharbieh; [2001]
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; non-linear diffusion filtering; optically dense sprays; curve evolution propagation; image sequence analysis; laser induced fluorescence; geodesic paths; level sets; LIF; optical density; spray characterization; flame propagation; laser; particle image velocimetry; spectroscopy; combustion engines; spray diagnostics; Mie scattering; flame fronts; laser attenuation; tracking; combustion diagnostics; curve matching; combustion; laser sheet imaging; PIV; time resolved imaging; segmentation;

    Abstract : This Thesis presents techniques that aim at exploiting the potential of image analysis and processing in order to solve problems of data reduction, interpolation, quantification, and interpretation within the field of experimental laser imaging of combustion processes. Combustion is the most important source of energy for power generation, heating, and transportation in the world today and its strong dominance is projected to continue in the foreseeable future.

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

    University dissertation from Stockholm : KTH Royal Institute of Technology

    Author : Seyed Hamid Tabaeikazerooni; Luca Brandt; Jeanette Hussong; Raffaella Ocone; [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

    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

  4. 4. 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; [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

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

    University dissertation from Lund Report on Combustion Physics

    Author : Jiajian Zhu; [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
