November 2006 Laserinduzierte Inkandeszenz für die Rußdiagnostik bei erhöhtem Druck Laser-induced incandescence for soot diagnostics at high pressure Gutachter: Prof. Dr. Jürgen Wolfrum Prof. Dr. Christof Schulz SUMMARY This work focuses on laser-induced incandescence (LII) at elevated pressure. LII is a laser-based technique for measuring particle sizes and volume fractions of nano-sized particles in aerosols. These particles, as emitted by traffic in the form of soot, cause a significant health risk, as nano-sized particles can penetrate deeply into the lungs and are considered important for causing asthma, fibrosis and the development of tumors [1,2]. Over the past 20 years, LII has been developed and applied mainly for soot diag-nostics in flames. However, only little work has been performed before on LII in sooting flames at elevated pressure.
