1. Laser Spectroscopic Techniques for Combustion Diagnostics Directed Towards Industrial ApplicationsDetta är en avhandling från Combustion Physics, Lund Institute of Technology
Sammanfattning : In the work presented in the thesis, different laser spectroscopic techniques were utilized for measurement of species concentrations, as well as for surface thermometry. Experiments were conducted in various combustion environments, ranging from laboratory burners to truck-sized internal combustion (IC) engines, gas turbine combustors and a full-size aircraft turbofan engine.

2. Development and application of laser diagnostics - from laboratory devices towards practical combustion enginesDetta är en avhandling från Division of Combustion Physics, Department of Physics, Lund University
Sammanfattning : For many decades, research work on combustion has been focused on improving combustion efficiency and reducing harmful emissions. Laser diagnostics is one of the best ways to investigate the combustion process and emission formation as it is non-intrusive and it has high spatiotemporal resolution. LÄS MER
- Detta är en avhandling från Division of Combustion Physics, Department of Physics, Lund University
Sammanfattning : 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.

- Detta är en avhandling från Department of Combustion Physics, Lund University
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
5. Development and Application of Rotational Coherent Anti-Stokes Raman Spectroscopy and Laser-induced Fluorescence for Combustion DiagnosticsDetta är en avhandling från Division of Combustion Physics, Department of Physics, Lund University
Sammanfattning : The thesis concerns the development and application of two laser-based methods for combustion diagnostics: dual broadband rotational coherent anti-Stokes Raman spectroscopy (CARS) and laser-induced fluorescence (LIF). In efforts to increase the usefulness of the CARS technique, the applicability of a method involving a combination of the rotational CARS technique and the closely related vibrational CARS technique was investigated.
