Texto completo
Numerous efforts have been made to develop gas turbine fuel injectors that premix methane/natural gas and air in fuel lean proportions prior to the reaction zone. Application of this technique to hydrogen combustion has been limited due to hydrogen's high flame rate and the concern of the reaction zone propagating into the premixing injector, commonly referred to as flashback. In this investigation, a lean-premixing hydrogen injector has been developed for application in small gas turbines. The performance of this injector was characterized and predictions about the injector's performance operating under combustor inlet conditions of a PT6-20 Turboprop have been made.

Texto completoAeronautical engine manufacturers are banking on the development of innovative fuel injection systems to reduce fuel consumption and pollutant emissions. The aim of the thesis is to contribute to the experimental investigation of a "Lean Premixed" injector by developing laser diagnostics coupling approaches based on Mie scattering and fluorescent emission of tracers. Measurements are performed at high pressure on the HERON combustion test bench. An innovative approach with fluorescence imaging of kerosene has resulted in the quantification of the kerosene/air mixture. The flame structure was analyzed simultaneously by OH-PLIF and velocity PIV measurements were performed to complete this analysis. A preliminary development of CO-PLIF was also conducted. The numerous measurements provided a detailed analysis of the mechanisms of flame/spray/aerodynamic interactions during a swirl-stabilized kerosene/air combustion at high pressure

The objective of this thesis is to investigate further into the spray characteristics of the gas-centered swirl injector, which is the injector type recently attracts intensive research interests and is to be used for Lox/Kerosene propellant combination for future economical green propulsion for various space applications. The experiment method used in this thesis include spray visualization, such as spray angle measurement and spray pattern identification, and planar laser induced fluorescence for spray mass distribution. The experimental parameters are the momentum flux ratio between central gas and co-axial swirl liquid, the recess ratio of the central tube relative to the coaxial outer tube and the environmental pressure. The experimental results show that when in atmospheric and high pressure conditions, the spray angle decreases as the momentum flux ratio and the recess ratio are increased. But the variation of spray angle in high pressure condition is smaller as compared to atmospheric condition. The spray pattern shows two distinct spray zones, the inner and outer zones, for cases of atmospheric condition, but the outer zone disappears as the increase of the recess ratio and momentum flux ratio. The planar fluorescence measurement results show that at atmospheric condition the mass distribution of the spray is asymmetric and the high density region become large as the momentum flux ratio and recess ratio are increased. When at high pressure condition, the spray is dominated by the inner zone, and the mass distribution is rather symmetric and the distribution becomes flat when the momentum flux ratio and recess ratio are increase. We conclude that this type of injector is recommended to operate at higher gas velocities to acquire good and uniform atomization. A key breakup mechanism for the gas-centered swirl coaxial injector is proposed based on the Kelvin-Helmholtz instability of the momentum flux ratio and the recess ratio between the central gas and the coaxial liquid. The length of the gas-centered coaxial injector’s mixing cup affects the key breakup mechanism and can significantly affect combustion efficiency.
