18. Laser-Induced Incandescence for Soot Diagnostics: Theoretical Investigation and Experimental Development
Sammanfattning : 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.

19. Laser-Induced Incandescence and Complementary Diagnostics for Flame Soot Characterization
Sammanfattning : 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. LÄS MER
20. Combustion Studies of Soot and Fuel Based on Use of Laser Diagnostics
Sammanfattning : In the work described in the present thesis, laser techniques for combustion engine diagnostics were developed and applied. The main techniques were laser-induced incandescence (LII) and laser-induced fluorescence (LIF), used for both flame and engine diagnostics. LÄS MER
