    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; turbulent combustion; PDA; swirl stabilisation; PIV; off-design.; Gas turbine; experimental methods; LDA; atomisation; emission measurements;

    Sammanfattning : The thesis aims to analyse the gas turbine based energy conversion systems with the emphasis on combustion chambers. The investigation is mainly experimental at a component level. The majority of investigations concentrate on gaseous fuel firing. LÄS MER

  3. 17. Application of Laser-based Diagnostics to a Prototype Gas Turbine Burner at Selected Pressures

    Författare :Ronald Whiddon; Förbränningsfysik; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; OH; Laser Diagnostics; Elevated Pressure; Syngas; DLE; NOx; Combustion; Gas Turbine; PIV; PLIF; Pilot; SGT-750; Fysicumarkivet A:2014:Whiddon;

    Sammanfattning : The matured laser-diagnostic techniques of planar laser-induced fluorescence (PLIF) and particle image velocimetry (PIV) were applied to a prototype gas turbine burner operating on various fuels. The work was performed to provide verification of computational fluid dynamic (CFD) models of the combustion of atypical fuels in a gas turbine combustor. LÄS MER

  4. 18. Prediction of Cooling Air Flow in Electric Generators

    Författare :Pirooz Moradnia; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; CFD; Multiple Reference Frame; PIV; Total Pressure Measurements; Electric Generator; Experimental Measurements; 5-hole Pressure Probe Measurements; Flow Prediction; OpenFOAM;

    Sammanfattning : The cooling air flow in hydro power electric generators is investigated experimentally and numerically. A fully predictive numerical approach is presented and validated, in which the inlet and outlet boundaries are eliminated from the computational domain. LÄS MER

  5. 19. Study of gas fuel jet burning in low oxygen content and high temperature oxidizer

    Författare :Magnus Mörtberg; Wlodek Blasiak; David G. Lilley; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Materials science; combustion; entrainment; jet in crossflow; PIV; ICCD; Materialvetenskap; Materials science; Teknisk materialvetenskap;

    Sammanfattning : During the past decade, new advanced combustion systems that share the same basic concept of using a substantially diluted and high-temperature oxidizer in the reaction volume have gained a great deal of interest regarding their application in industrial and power systems. These novel combustion technologies have proved to offer significant benefits compared to traditional combustion techniques. LÄS MER

  7. 20. An Experimental Study of Fluid Dynamics and Mixing in Bubbly Gas-Liquid Flow Systems

    Författare :Jafar Sadegh Moghaddas; Livsmedelsteknik; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Bubbly flow; PLIF; Two-phase flow; PIV; Gases; plasmas; Gaser; fluid dynamics; fluiddynamik; plasma; Mixing;

    Sammanfattning : In the present project, a new experimental method enabling Planar Laser-Induced Fluorescence (PLIF) measurements in bubbly gas-liquid flows is presented. Due to reflection and refraction of the laser light, the bubbles will cause an uneven and unknown distribution of light intensity in the measurement plane. LÄS MER
