  2. 1. Numerical and experimental investigation of a gasturbine model combustor with axial swirler

    Author : Michael Bertsch; Strömningsteknik; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; flashback; swirl; gasturbine; combustor; methane; hydrogen; LES; PLIF;

    Abstract : This thesis presents the simulations of and experiments with the so-called CECOST burner. The CECOST burner is a gas turbine model combustor equipped with an axial swirler and placed in a laboratory for the lean premixed turbulent combustion of a range of fuels at atmospheric pressure.

  4. 2. Application of Laser Techniques in Combustion Environments of Relevance for Gas Turbine Studies

    Author : Andreas Lantz; Förbränningsfysik; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Laser Diagnostics; PLIF; Laser-Induced Fluorescence; Combustion; Fuel visualization; LIF; Gas turbine; Flashback; Flame position; Swirling flame; Fysicumarkivet A:2012:Lantz;

    Abstract : In the work presented in this thesis, different laser-based techniques were employed for measurements in different combustion devices. Laser-based techniques enable non-intrusive and in-situ measurements to be carried out, in which high spatial and temporal resolution can be obtained. READ MORE

  5. 3. Laser-Based Investigations of Combustion Phenomena in Gas Turbine Related Burners

    Author : Arman Subash; Förbränningsfysik; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Combustion; Gas turbine; Chemiluminescence; laser-based techniques; LIF; PIV; DLE; TARS; CH4; H2; OH; CH20; Equivalence ratio; flame stabilization; LBO; Flashback; RPL; Fysicumarkivet A:2018:Subash;

    Abstract : Experiments were performed on various combustion devices to investigate the flames employing different optical measurement techniques under atmospheric pressure conditions. Non-intrusive laser-based techniques provided in-situ information concerning different parameters of the combustion process, with a high degree of temporal and spatial resolution. READ MORE

  6. 4. Experimental and Numerical Investigations of Flames Stabilized by Swirl Flow and Bluff-body:Flame Structures and Flame Instabilities

    Author : Yiheng Tong; Kraftverksteknik; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Flame structures; Flame instabilities; Blowout limits; Flashback; Swirl Flow; Bluff-body; Chemiluminescence; PIV;

    Abstract : Combustion and its control are essential to our existence on this planet since we knew it. Nowadays, the largest share of the world’s electricity and most of our transportation systems are powered by combustion. In addition, industrial processes also rely heavily upon combustion.

  7. 5. Operational stability of lean premixed combustion in gas turbines : an experimental study on gaseous alternative fuels

    Author : Parisa Sayad; Kraftverksteknik; []
    Keywords : Premixed Combustion; Syngas; Swirl Stabilized; Chemical Kinetics; Flashback; Lean Blowout; Autoignition; OH*-chemiluminescence;

    Abstract : World electricity consumption is drastically increasing. One of the most common ways of producing electricity is to use the chemical energy of fossil fuels. This can be done in thermal power plants in which the chemical energy of fossil fuels such as natural gas is converted to mechanical energy and finally to electricity. READ MORE
