  1. 1. Application and Development of Optical Soot Diagnostic Techniques

    Author : Ted Lind; Förbränningsmotorer; []
    Keywords : Soot; Soot diagnostics; Soot oxidation; Extinction Imaging; Soot thermometry; Optical diagnostics;

    Abstract : Internal combustion engines (ICE) have been a vital part of society ever since their inception more than a hundred years ago. While initially it seemed as if the replacement of horse and carriage had solved the issue with pollutant emissions, it became evident in the 60’s that emission from ICEs is a major concern.

  2. 2. Development of a 2D Temperature Measurement Technique for Combustion Diagnostics using 2-Line Atomic Fluorescence

    Author : Johan Engström; Förbränningsfysik; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Laser technology; Elektronik och elektroteknik; Electronics and Electrical technology; PLIF; LIF; temperature measurements; TLAF; Laser diagnostic; combustion; Laserteknik; Motors and propulsion systems; Motorer; framdrivningssystem;

    Abstract : The present thesis is concerned with the development and application of a novel planar laser-induced fluorescence (PLIF) technique for temperature measurements in a variety of combusting flows. Accurate measurement of temperature is an essential task in combustion diagnostics, since temperature is one of the most fundamental quantities for the characterization of combustion processes.

    Abstract : Various laser diagnostic techniques have been developed and demonstrated for engine, or engine-related measurements. The experimental work is presented in Chapter 3 and in Papers I-VII. In Chapter 3, imaging of soot in a running compression-ignition (CI) is described. READ MORE

  4. 4. Development of Multi-Dimensional Laser Techniques for In-situ Combustion Diagnostics

    Author : Jenny Nygren; Förbränningsfysik; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Laser Diagnsotics; Visualisation; Laser technology; Laserteknik; Motors and propulsion systems; Motorer; framdrivningssystem; Combustion; Temperature; Fysicumarkivet A:2003:Nygren;

    Abstract : Multi-dimensional, laser-based measurements of quantities important for obtaining a better understanding of combustion processes, particularly of temperature and of species distributions, were performed using laser-induced fluorescence (LIF). The main purpose of the temperature experiments was to investigate the potential of employing a two-line atomic fluorescence technique (TLAF), using indium as the tracer species, in sooting environments such as in diesel engines.

  5. 5. Development and Application of Single-Ended Picosecond Laser Diagnostics

    Author : Billy Kaldvee; Förbränningsfysik; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Raman Scattering; Temporal Filtering; Picosecond Laser Diagnostics; Rayleigh Scattering; Laser-spectroscopy; DIAL; Laser Combustion Diagnostics; Lidar; Laser-induced Fluorescence; Laser-induced Incandescence; Fysicumarkivet A:2012:Kaldvee;

    Abstract : Light detection and ranging (lidar), a method for nonintrusive, single-ended, and range resolved measurements, has been developed and applied for combustion related diagnostics. Employing picosecond laser pulse durations and detectors providing temporal resolution on the order of picoseconds, lidar has been applied successfully for both quantitative temperature- and species concentration measurements, obtaining an ultimate range resolution of 0.
