1. High Repetition Rate Laser Diagnostics for Combustion Applications
Sammanfattning : High repetition rate laser diagnostics has proven to be a useful tool for studying combustion phenomena. Laser techniques are, in general, relatively non-intrusive and have the potential to measure specific species at very low concentrations and with extremely high temporal resolution. LÄS MER
2. Development of Laser-Induced Fluorescence for Precombustion Diagnostics in Spark-Ignition Engines
Sammanfattning : Motivated by a desire to understand and optimize combustion in spark-ignition (SI) engines, laser techniques have been developed for measurement of fuel and residual gas, respectively, in the precombustion mixture of an operating SI engine. The primary objective was to obtain two-dimensional, quantitative data in the vicinity of the spark gap at the time of ignition. LÄS MER
3. Material migration in tokamaks: Studies of deposition processes and characterisation of dust particles
Sammanfattning : Thermonuclear fusion may become an attractive future power source. The most promising of all fusion machine concepts is the tokamak. Despite decades of active research, still huge tasks remain before a fusion power plant can go online. One of these important tasks deals with the interaction between the fusion plasma and the reactor wall. LÄS MER
4. Characterization of the Homogeneous Charge Compression Ignition Combustion Process
Sammanfattning : The main objective of this project was to characterize the HCCI combustion process. Central parts in the project were the progress of the HCCI combustion process, the influence of charge homogeneity on the combustion process and sources of UHC and CO emissions in HCCI combustion.
