  1. 1. Thermo-Acoustic Properties in Combustion Chambers

    Author : Guillaume Jourdain; [2010]
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Mode Stability Analysis; Computational Aeroacoustics; Screech mode; Arnoldi s Method; Buzz mode; Afterburner; Gas turbine combustor; Combustion instabilities;

    Abstract : Design and analysis methods for gas turbine combustors or afterburners have to be improved in particular regarding the prediction of combustion instabilites. A methodology, which combines the use of a linearized flow solver and an Arnoldi algorithm performing the eigenmode extraction procedure, resolves eigenmodes which are candidates to these instabilities.

  2. 2. Laser Spectroscopic Techniques for Combustion Diagnostics Directed Towards Industrial Applications

    University dissertation from Combustion Physics, Lund Institute of Technology

    Author : Hans Seyfried; [2007]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Teknik; Technological sciences; Fysik; Physics; Combustion; Gas turbine; HCCI; Engine; High-Speed; Thermographic phosphors; PLIF; LIF; Laser Diagnostics; Laser-Induced Fluorescence; Laser technology; Laserteknik; Motors and propulsion systems; Motorer; framdrivningssystem;

    Abstract : In the work presented in the thesis, different laser spectroscopic techniques were utilized for measurement of species concentrations, as well as for surface thermometry. Experiments were conducted in various combustion environments, ranging from laboratory burners to truck-sized internal combustion (IC) engines, gas turbine combustors and a full-size aircraft turbofan engine.

  3. 3. Liquid scintillators as neutron diagnostic tools for fusion plasmas System characterization and data analysis

    University dissertation from Uppsala : Acta Universitatis Upsaliensis

    Author : Federico Binda; Uppsala universitet.; [2018]

    Abstract : The neutrons produced in fusion devices carry information about various properties of the ions that are reacting in the machine. Measurements of the neutron flux and energy distribution can therefore be used to study the behaviour of the plasma ions under different experimental conditions. READ MORE

  4. 4. Laser-Induced Emission Techniques for Concentration and Temperature Probing in Combustion

    University dissertation from Division of Combustion Physics, Department of Physics, Lund University

    Author : Gustaf Särner; [2008]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; thermographic phosphor; phosphor; phosphorescence; Laser Combustion Diagnostics; Laser-Spectroscopy; LIF; spectroscopy; Thermometry; LIP; Laser-Induced Fluorescence;

    Abstract : The work in this thesis is aimed at the development of temperature and gas concentration measurement techniques in laser diagnostics for use in combustion research. The techniques are developed as tools for the combustion community to meet future demands on combustion efficiency and legislation of exhaust gases. READ MORE

  5. 5. Persistent Organic Pollutants and the Environment : A Chemometric Approach to the Study of Halogenated Aromatics

    University dissertation from Division of Combustion Physics, Department of Physics, Lund University
