  2. 1. High Repetition Rate Laser Diagnostics for Combustion Applications

    Author : Johan Sjöholm; Förbränningsfysik; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; spray; diesel; optical engine; simultaneous; laser-induced fluorescence; fuel tracer; SLIPI; Raman; LII; laser diagnostic; combustion; high repetition rate; high-speed; PLIF; multi-YAG; LIF; fuel jet; Fysicumarkivet A:2012:Sjöholm;

    Abstract : High repetition rate laser diagnostics has proven to be a useful tool for studying combustion phenomena. Laser techniques are, in general, relatively non-intrusive and have the potential to measure specific species at very low concentrations and with extremely high temporal resolution. READ MORE

  4. 2. Laser Diagnostic Techniques with Ultra-High Repetition Rate for Studies in Combustion Environments

    Author : Jimmy Olofsson; Förbränningsfysik; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; High-Speed; High Repetition Rate; LIF; PLIF; 3D Visualisation; Engine; Teknik; Technological sciences; Fysik; Physics; Combustion; Laserteknik; Laser technology; Laser-Induced Fluorescence; Laser Diagnostics;

    Abstract : When conducting laser based diagnostics in combustion environments it is often desirable to obtain temporally resolved information. This can be due to several factors such as combustion taking place in a turbulent flow field, flame propagation from a spark plug in an initially quiescent combustible mixture, or rapid, multi-point fuel consumption in a homogeneous charge as a result of compression ignition in an engine cycle.

  5. 3. OH and Soot Optical Diagnostics for Combustion Applications for Combustion Applications

    Author : Zheming Li; Förbränningsfysik; []
    Keywords : laser-induced fluorescence spectroscopy; Soot emission; combustion diagnostics; Fysicumarkivet A:2016:Li;

    Abstract : Optical diagnostics are remote non-intrusive sensing techniques. The thesis work concerns the use of OH and soot optical diagnostics for combustion research.Internal combustion (IC) engines are widely used for the generation of power and for transportation purposes. READ MORE

  6. 4. 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
