  1. 1. Laser Diagnostics for Applications to In-Cylinder Engine Investigations

    Författare :Robert Collin; Förbränningsfysik; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; LII; Rayleigh scattering; formaldehyde; OH; soot; dimethyl ether; Laser technology; Fysik; Laserteknik; Physics; LIF; Laser diagnostics; combustion engines; Fysicumarkivet A:2004:Collin;

    Sammanfattning : In the work presented in the thesis laser diagnostics was employed primarily in the investigation of engines, but was also used to study soot in flames. Quantitative measurements were performed for visualizing both in-cylinder soot formation and DME sprays in a combustion vessel. LÄS MER
