6. Laser-Based Investigations of Combustion Phenomena in Gas Turbine Related Burners
Sammanfattning : Experiments were performed on various combustion devices to investigate the flames employing different optical measurement techniques under atmospheric pressure conditions. Non-intrusive laser-based techniques provided in-situ information concerning different parameters of the combustion process, with a high degree of temporal and spatial resolution. LÄS MER
7. Investigation of a prototype industrial gas turbine combustor using alternative gaseous fuels
Sammanfattning : In this thesis, the effect of alternative gaseous fuels, with high hydrogen content and lower calorific value, on gas turbine combustion was investigated experimentally. The aim of the investigation was to find operational limitations for an experimental burner and to supply data for validation of computational fluid dynamics (CFD). LÄS MER
