  2. 1. Laser-Induced Incandescence for Soot Diagnostics: Theoretical Investigation and Experimental Development

    Author : Jonathan Johnsson; Förbränningsfysik; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; premixed flat flames; fractal soot aggregates; laser-induced incandescence; soot; soot optical properties; soot absorption function; laser diagnostics; Fysicumarkivet A:2012:Johnsson;

    Abstract : Laser-induced incandescence, LII, is a laser-diagnostic technique that can be used to measure the volume fraction and the sizes of soot particles suspended in a gas, such as within a combustion process or in its exhausts. The technique is based on the facts that the time-decay of the radiation from laser-heated soot particles is directly related to the particle size in the probed volume, and that the time-integrated radiation is related to the soot volume fraction.

  4. 2. Laser-based diagnostics for investigating soot formation in combustion processes

    Author : MANU Mannazhi; Förbränningsfysik; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Soot formation; Laser diagnostics; Combustion; Laser-induced Incandescence; Fysicumarkivet A2022:Mannazhi;

    Abstract : In this work, laser-based diagnostic techniques were developed and applied to investigate soot formation in small-scale laboratory burners as well as in practical combustion devices. Quantitative 2D laser-induced incandescence (LII) measurements often use a cylindrical lens to shape the beam and illuminate the planar region of interest. READ MORE

  5. 3. Laser-Induced Incandescence and Complementary Diagnostics for Flame Soot Characterization

    Author : Nils-Erik Olofsson; Förbränningsfysik; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Fysicumarkivet A:2015:Olofsson;

    Abstract : This work has been aimed at developing and applying laser-induced incandescence (LII) for flame soot characterization. The basic principle of LII is rapid heating of the soot particles to temperatures of 3500-4000 K by short laser pulses. Thereby the intensity of the soot incandescence is increased. READ MORE
